media: uvcvideo: Fix deferred probing error
uvc_gpio_parse() can return -EPROBE_DEFER when the GPIOs it depends on
have not yet been probed. This return code should be propagated to the
caller of uvc_probe() to ensure that probing is retried when the required
GPIOs become available.
Currently, this error code is incorrectly converted to -ENODEV,
causing some internal cameras to be ignored.
This commit fixes this issue by propagating the -EPROBE_DEFER error.
