usb: gadget: core: force synchronous registration 



Registering a gadget driver is expected to complete synchronously and
immediately after calling driver_register() this function checks that
the driver has bound so as to return an error.

Set PROBE_FORCE_SYNCHRONOUS to ensure this is the case even when
asynchronous probing is set as the default.
