Static code analyser detects uninitialized pointer/structure
access and dereferencing a pointer without null check.
As part of this fix host will initialize pointer/structure before
accessing it and put a null check for pointer access.

Host should avoid to Update MC list in ftm mode because
as a part of MC list updation, host will access the
pMac roam sessions, as these sessions are not initialized
in FTM mode which lead to Null data access.

Kernel assumes all SET IOCTL commands are assigned with even
numbers. But in our WLAN driver, some SET IOCTLS are assigned with
odd numbers. This leads kernel fail to check, for some SET IOCTLs,
whether user has the right permission to do SET operation.
Hence, in driver, before processing SET_VAR_INTS_GETNONE, making
sure user task has right permission to process the command.

As a part of unload hdd is stopping the netdev queue.
But still N/W layer 3 is calling the select queue netdev
ops, where error print for sap context is Null appears
excessively.
As a part of this fix hostap select queue need to validate
Hdd context to take care of SSR and load / unload cases.

While adding pStaDs for IBSS when peer beacon is received, HT
secondary channel offset is not copied from beacon. This leads to
false change capability indication while processing the same beacon
and thus update cb mode is sent with staid 255(default),
leading to crash.
Update HT secondary channel offset from beacon and add a check in
cbmode update to ignore update if staid is 255.

Ensure lock is taken before accessing the DFS shared variable.

Host driver updates WLAN status to LPASS with connected false and WLAN on
when disconnection happens. Host driver also updates WLAN status right
after driver unload is triggered with connected false and WLAN off. There
is a scenario that disconnection callback comes during driver unloading
which causes LPASS misbehavior. Fix this by only updating disconnection
status to LAPSS when driver is not unloading.

Increase SSR timeout from 15 seconds to 30 seconds in order to handle

- Kill wlan_tasklet before freeing TLshim free queue. This can avoid
race condition between SSR and wlan_tasklet which is still processing
Rx packets in the case of self-recovery when FW doesn't really crash.
- In additional to connected state, add disconnected/disconnecting states
to send notification to supplicant for re-issuing connect after SSR.
This is to avoid corner cases that while FW crashes, disconnection is
happening or disconnection fails because of FW crash, the HDD state is
changed from connected to disconnecting/disconnected.
