media: uvcvideo: Propagate buf->error to userspace
Now we return VB2_BUF_STATE_DONE for valid and invalid frames. Propagate
the correct value, so the user can know if the frame is valid or not via
struct v4l2_buffer->flags.

Closes: https://lore.kernel.org/linux-media/84b0f212-cd88-46bb-8e6f-b94ec3eccba6@redhat.com
