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.
