avformat/shared: use strong CAS for marking PENDING
This was using a weak atomic under the assumption that the `goto retry`
will immediately jump back to the same line. However, that's no longer
true after the introduction of the `read_block` label, which we can
jump to from the error handling fallback path.

In this case, we really ought to use a strong CAS to ensure that we
only re-check the state if it truly changed in the meantime.
