Subject: mwifiex: fix NULL pointer dereference during hidden SSID scan

From: Aniket Nagarnaik <[email protected]>

commit 17e524b1b60f4390d24a51d9524d1648cf5d1447 upstream.

This NULL pointer dereference is observed during suspend resume stress test. All pending commands are cancelled when system goes into suspend state. There a corner case in which host may receive response for last scan command after this and try to trigger extra active scan for hidden SSIDs.

The issue is fixed by adding a NULL check to skip that extra scan.
