mwifiex: fix memory leak issue when driver unload
After unregister_netdevice() call the request is queued and reg_state is changed to NETREG_UNREGISTERING. As we check for NETREG_UNREGISTERED state, free_netdev() never gets executed causing memory leak. Initialize "dev->destructor" to free_netdev() to free device data after unregistration.
