Bluetooth: silence lockdep warning

Since bluetooth uses multiple protocols types, to avoid lockdep
warnings, we need to use different lockdep classes (one for each
protocol type).

This is already done in bt_sock_create but it misses a couple of cases
when new connections are created. This patch corrects that to fix the
following warning:

Bluetooth: l2cap_set_timer needs jiffies as timeout value

After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
value to be specified in jiffies but constants defined in miliseconds
are used. This makes timeouts unreliable when CONFIG_HZ is not set to
1000.

__set_chan_timer macro still uses jiffies as input to avoid multiple
conversions from/to jiffies for sk_sndtimeo value which is already
specified in jiffies.

However, this broke l2cap conn establishment for ssp remote devices

zd1211rw: firmware needs duration_id set to zero for non-pspoll frames

Some devices (iwl5100) cannot connect to zd1211rw based AP. It appears that
zd1211 firmware messes up duration_id field if it is not set to zero by driver.

Sniffing traffic shows that zd1211 is transmitting frames with duration_id bits
14 and 15 set and other bits appearing random. Setting duration_id at driver to
zero results zd1211 outputting sane duration_id. This means that firmware is
setting correct values itself and expects duration_id to be zero in first
place.

Looking at vendor driver shows that only PSPoll frames have duration_id set by
driver, for other frames duration_id left zero.

mac80211: call rate control only after init

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.

mwifiex: update correct dtim_period in dump_station()

Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.

After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.

Redundant code after adapting new approach for dtim period is
also removed in this patch.

mac80211: support hw scan while idle

Currently, mac80211 goes to idle-off before starting a scan.
However, some devices that implement hw scan might not
need going idle-off in order to perform a hw scan, and
thus saving some energy and simplifying their state machine.

(Note that this is also the case for sched scan - it
currently doesn't make mac80211 go idle-off)

Add a new flag to indicate support for hw scan while idle.
