Bluetooth: hidp: Stop I/O on shutdown
Current hidp driver purges the in/out queue on HID shutdown, but does
not prevent further I/O. If a driver uses hidp_output_raw_report or
hidp_get_raw_report during shutdown, the driver hangs for 5 or 10
seconds per call until it gets a timeout.
That is, if the output queue of an HID driver has 10 messages pending,
it will take 50s until hid_destroy_device() will return. The
hidp_session_sem semaphore is held during shutdown so no other HID
device may be added/removed during this time.
This patch makes hidp_output_raw_report and hidp_get_raw_report fail if
session->terminate is true. Also hidp_session will wakeup all current
calls to these functions to cancel the current operations.

Bluetooth: Allow ACL packets over USB in HCI_RAW mode
Removed tests which prevent transmission of ACL packets
when the device is in HCI_RAW mode. These tests verified that
there are ACL or LE links currently tracked by the HCI
connection manager. However, a HCI_RAW mode device does not
use the connection manager. In these circumstances, the connection
counts will be zero, and thus, transmitted ACL packets dropped.
The acl_num test is actually a vestige of a previous bulk URB
scheme that is no longer used by this driver (bulk URBs were not
started until at least one ACL connection was created). This was
incompatible with some endpoint implementations and was dropped -
see commit
43c2e57f94.
The utility of these tests is marginal - currently, the hci tx
scheduler cannot send an ACL or LE packet for an untracked connection
(except if the device is in HCI_RAW mode).
Lastly, no other transport layer driver enforces these same tests.

Event sending is handled in mgmt_device_blocked function which gets
