usb: misc: uss720: properly clean up reference in uss720_probe()

Browse Source 
If get_1284_register() fails, the usb device reference count is
incorrect and needs to be properly dropped before returning.  That will
happen when the kref is dropped in the call to destroy_priv(), so jump
to that error path instead of returning directly.
