wifi: libertas: Fix possible refcount leak in if_usb_probe()

Browse source 
[ Upstream commit 6fd57e1d12 ]

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: ce84bb69f5 ("libertas USB: convert to asynchronous firmware loading")
