USB: musb: gadget: set otg tranceiver to idle when registering gadget
When registering gadget driver, the state of the transceiver must be set from undefined (no gadget) to b_idle. Module unload sets the transceiver state to undefined state. After the first load/unload pair, the reset irq will be lost.
