drivers: usb: smsusb: fix error handling code in smsusb_init_device

[ Upstream commit b9c7141f384097fa4fa67d2f72e5731d628aef7c ]

The previous commit 4b208f8b561f ("[media] siano: register media controller
earlier")moves siano_media_device_register before smscore_register_device,
and adds corresponding error handling code if smscore_register_device
fails. However, it misses the following error handling code of
smsusb_init_device.

Fix this by moving error handling code at the end of smsusb_init_device
and adding a goto statement in the following error handling parts.
