mac80211: fix TX aggregation session timer
In commit 12d3952fc4a1cd96234bc7023bf7eefeb0bb6355
("mac80211: optimize aggregation session timeout handling")
two bugs were introduced:
1) RCU usage was completely broken since no locks are held
2) the timer must not rearm when agg session is stopping

brcmfmac: remove redundant retries for SDIO core register access
The new brcmf_sdio_regrl/regwl interface has already performed
retries on failed attempts. It is no longer necessary to have the
retry mechanism in r_sdreg32/w_sdreg32.

This patch fixes multiple issues with the current RTT
implementation in ath9k.
* The data that is obtained from the RTT interface registers
are stored in 31:5 - mask out the extra bits when reading them.
* A history buffer is maintained which is not needed at all.
Remove this array and just store the baseband data for each
chain (or bank).
* A 'num_readings' variable was being used to handle the
last entry. But it was being used in an improper manner, with
the result that the RTT values were never being written
to the RTT Interface registers. Fix this by using a simple
flag.
* Stop baseband operations before programming the calibration values
to the HW.
* Do not restore RX gain settings as part of RTT.

iwlwifi: don't disable AGG queues that are not enabled
If the BA session is torn down before we had a chance to start it
we shouldn't disable the AGG tx queues that weren't enabled.
This can happen in two cases:
1) We get a delBA before we drained our Tx queues in agg start flow
2) We didn't get the (successfull) addBA response on time

Drivers need to report the number of transmission attempts for each rate
as well as to terminate the rate array with -1. The in-kernel datapath
of hwsim simulates a perfect medium, therefore the driver only needs to
report that the first transmission attempt was sucessfully completed at
the most favorable rate.
