Xinming Hu bcf28a2f28 mwifiex: reset card->adapter during device unregister
card->adapter gets initialized in mwifiex_register_dev(). As it's not
cleared in mwifiex_unregister_dev(), we may end up accessing the memory
which is already free in below scenario.

Scenario: Driver initialization is failed due to incorrect firmware or
some other reason. Meanwhile device reboot/unload occurs.

This is safe, now that we've properly synchronized suspend() and
remove() with the FW initialization thread; now that code can simply
check for 'card->adapter == NULL' and exit safely.
