mwifiex: move del_timer_sync(scan_delay_timer) call to fix memleak
Currently it is in mwifiex_adapter_cleanup() which doesn't get
called if driver initialization is failed causing memory leak.
scan_delay_timer is initialized in mwifiex_register(), so it
should be deleted in mwifiex_unregister(). Hence it has been
moved to appropriate place.
