When deinitializing the driver, one or more "FW not responding" error appears on the console. This appears to be due to wilc_wlan_stop() disabling host/WILC1000 communication, but then right afterwards, it tries to release the bus with chip-sleep enabled. The problem is enabling the chip-sleep cannot success once host/WILC1000 communication is disabled. Fix by only releasing the bus.
