wifi: libertas: Fix possible refcount leak in if_usb_probe()
[ Upstream commit 6fd57e1d120bf13d4dc6c200a7cf914e6347a316 ]
usb_get_dev will be called before lbs_get_firmware_async which means that
usb_put_dev need to be called when lbs_get_firmware_async fails.
Fixes: ce84bb69f50e ("libertas USB: convert to asynchronous firmware loading")
