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.
