avcodec/v4l2_context: suppress POLLERR and fix crash when buffers are uninitialized
A POLLERR occurs when libavcodec attempts to dequeue output buffers before enqueuing capture buffers. This could happen to an application deciding to send the first coded packet. Suppress these POLLERRs when the buffers are uninitialized and avoid crashing because of enumerating uninitialized buffers. See https://trac.ffmpeg.org/ticket/9957 for the original bug report.
