usb: gadget: uvc: verify descriptors presence

Browse source

If the caller of uvc_alloc() does not provide enough
descriptors, binding the function should fail, so appropriate
code is returned from uvc_copy_descriptors().

uvc_function_bind() is modified accordingly to account for possible
errors from uvc_copy_descriptors().
