Title:
Redpine: firmware assert upon assoc timeout

Status in linux package in Ubuntu:
Invalid
Status in linux source package in Xenial:
Fix Committed

Bug description:
SRU Justification
-----------------

Impact:
-------
firmware assert upon assoc timeout

Test Case:
----------
1) Bring up the Redpine Module in Coex mode 13.
2) Try to do roaming between two AP's.
3) At some point, When Association timeout happens and station tries to scan and
observed below firmware assert.
wlan0: authenticate with ac:a3:1e:a1:1e:85
wlan0: send auth to ac:a3:1e:a1:1e:85 (try 1/3)
wlan0: authenticated
wlan0: associate with ac:a3:1e:a1:1e:85 (try 1/3)
wlan0: associate with ac:a3:1e:a1:1e:85 (try 2/3)
wlan0: associate with ac:a3:1e:a1:1e:85 (try 3/3)
wlan0: association with ac:a3:1e:a1:1e:85 timed out
ven_rsi_91x: rsi_disable_ps: Cannot accept disable PS in PS_NONE state
ven_rsi_91x: rsi_interrupt_handler: ==> FIRMWARE Assert <==
ven_rsi_91x: rsi_interrupt_handler: Firmware Status is 0xa
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

RCA:
----
Root cause: When association starts, driver is sending station add peer
notify to firmware but when Association timeout happens, driver is not
sending station peer delete to Firmware. Hence, FW is going into DEEP SLEEP
in associated state, which is incorrect.

Fix:
----
Sending station delete peer notify when assoc timeout happens.

Regression potential:
---------------------
Ran roaming between two AP's for 20 hours and didn't see the issue.
