pixdesc: Improve scoring for opaque/unknown pixel formats
Hardware pixel formats do not tell you anything about their actual contents, but should still score higher than formats with completely unknown properties, which in turn should score higher than invalid formats. Do not return an AVERROR code as a score. Fixes a hang in libavfilter where format negotiation gets stuck in a loop because AV_PIX_FMT_NONE scores more highly than all other possibilities.
