[PATCH] v4l2bufferpool: Keep the GstPollFD around and check errors


Thsi is not yet fully correct yet, as we simply retry on error, which can
spin, until the driver has recovered. The pool will be in error if the signal
is lost, or if there is not enough buffers. I see EINVAL in errno for the later
but haven't find anything int he V4L2 spec that would confirm. A GAP
should be send instead of retrying now.
