vd_lavc: fix stall with some uses of --hwdec=copy

Also a regression of the filter change. The new code is more picky about
EOF states, and it turns out the weird delay queue (used with some hwdec
copy back modes only) accidentally dropped an EOF event. It reset the
avctx before the delay queue was drained, which meant it never returned
the expected AVERROR_EOF status code.

Also don't signal EOF when copy back fails. It should just try to
continue until fallback is performed.
