iwlwifi: mvm: Increase the max remain on channel time

Increase the maximal remain on channel time as longer remain
on channel requests are handled by the FW using fragmented
time events.

This reduces the number of user/kernel space iterations during
flows such as p2p_listen. In addition it is currently required
for flows which require longer duration such as p2p_sd.

rt2x00: Fix tx status reporting for reordered frames in rt2800pci

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.

For example a tx queue
[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.

To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.

This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.

Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header
alignment' in the patch "Fix buffer alignment for scatter-gather
I/O"(1df94a857), there exists the bytes loss issue which means that it will be
truncated 3 bytes in the transmitted file contents if a file which has over MTU
size is transferred through TCP/IP stack.  It doesn't look like TCP/IP stack
bug of 3.5 or the latest version of kernel but the byte alignment issue.  This
patch is to use the roundup() function for the byte alignment rather than the
predefined ATH6KL_HTC_ALIGN_BYTES.

ath6kl: remove false check from ath6kl_rx()

Dan found a check from ath6kl_rx() which doesn't make any sense at all:

"  1327          if (status || !(skb->data + HTC_HDR_LENGTH)) {
                                ^^^^^^^^^^^^^^^^^^^^^^^^^^
skb->data is a pointer.  This pointer math is always going to be false.
Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?"

I don't know what the check really was supposed to do, but I think Dan's guess
is right. Fix it accordingly.

ath6kl: add tracing support to debug message macros

Now all log messages are sent through the tracing infrastruture as well.
Tracing point doesn't follow debug_mask module parameter, instead it sends
all debug messages, so once you enable ath6kl_log_dbg tracing point you will
get a lot of messages. Needs to be discussed if this is sensible or not.
The overhead should be small enough and we anyway include debug level as
well so it's easy to filter in user space.

I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided
that it also sends the buffer to user space. But most likely in the future
