avcodec/h264dec: Properly mark frames as recovered when draining 

When decoding starts at a SEI recovery point very shortly before the
end of the video stream, there can be frames which are decoded before
the recovery point's frame is output and which will only be output once
the draining has started. Previously, these frames would never be set
as recovered. This commit copies the logic from h264_select_output_frame
to send_next_delayed_frame to properly mark such frames as recovered.

Fixes ticket #10936.
