mwifiex: fix crash during simultaneous scan and connect

If 'iw connect' command is fired when driver is already busy in
serving 'iw scan' command, ssid specific scan operation for connect
is skipped. In this case cmd wait queue handler gets called with no
command in queue (i.e. adapter->cmd_queued = NULL).

This patch adds a NULL check in mwifiex_wait_queue_complete()
routine to fix crash observed during simultaneous scan and assoc
operations.

Since we configure all the queues as CHAINABLE, we need to update the
byte count for all the queues, not only the AGGREGATABLE ones.

Not doing so can confuse the SCD and make the fw assert.

HT40 after associated

Fix the case of HT40 after association on specified AP, but it break the
association for some APs and cause not able to establish connection.
We need to address HT40 before and after addociation.

Command cancel path cancels the current command and moves
it to free command queue. While doing that it deletes the
command entry from the pending list. This is not correct
as the entry has been already deleted from the pending
list at 'mwifiex_exec_next_cmd'. Fixing it.

Also making sure the stale command pointer is cleaned and
unaccessible for later use.
