Explicitly check for bps == 0 when applying replaygain

During application of replaygain, bps is checked to be > 0. This
should never happen in a valid file. This check is specific for
replaygain application instead of more generic (at streaminfo)
because we still want to be able to recover files in which
streaminfo is invalid or missing.
