Fix sending and receiveing protected managment frames.
Lack of protected flag for received protected action frames
causes report these frames as unprotected robust action frames.
If the driver in AP mode sent frame with protected flag and
CCMP header using IEEE80211_KEY_FLAG_SW_MGMT_TX flag,
the FW encrypted frames once again. From user side all
received SA Query Requests and Responses were skipped and
all protected action frames were sent as malformed packets.

If 20MHz CAC completed successfully then
subsequent CAC with wider bandwidth (40Mhz, 80Mhz)
with identical control frequency did not start
monitor vdev making it impossible to detect any
radar pulses during intended CAC.
It also was incorrect to assume ath10k_config() will
be called after CAC is finished. Theoretically for
non-HT channels nothing changes between CAC and
start_ap() (albeit in practice this can be
different). The incorrect assumption led to CAC
not being stopped on non-HT chandefs leading to
all Rx being drooped making it impossible for
clients to associate.
While at it clean up the code a bit.

Signed-off-by: Johannes Berg <johannes.berg@intel.com>
It was possible to create/delete/start/stop
monitor vdev from a few places that were not
exclusively protected against each other. This
resulted in monitor vdev being stopped/removed by
one call origin while another one was expecting it
to continue running.
For example if CAC was started and interface's
promiscuous mode was toggled monitor vdev was
removed from the driver meaning no radar would be
detected. In additional a warning would be printed
upon CAC completion complaining it tried to stop
non-running monitor vdev.
The patch simplifies monitor code by removing
IEEE80211_HW_WANT_MONITOR_VIF (which wasn't really
ever needed) and improves state tracking. It also

by network stack and send back with access category 0. FW changes
