vd_lavc: make hwdec fallback message more consistent

The "rule" is that a fallback warning message should be shown only shown
if software decoding was used before, or in other words when either
hwdec was enabled before, but the stream suddenly falls back, or it was
attempted to enable it at runtime, and it didn't work.

The message wasn't printed the first time in the latter case, because
hwdec_notified was not set in forced software decoding mode. Fix it with
this commit. Fortunately, the logic becomes simpler.
