usb: gadget: core: force synchronous registration
commit df9158826b00e53f42c67d62c887a84490d80a0a upstream.
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.
Fixes: fc274c1e99731 ("USB: gadget: Add a new bus for gadgets")
