USB: otg: Fix bug on remove path without transceiver
In the case where a gadget driver is removed while no
transceiver was found at probe time, a bug in
otg_put_transceiver() will trigger.
Provide symetric calls for otg_get_transceiver() and
otg_put_transceiver(), wherever a transceiver was found or
not.
