When ff_h264_decode_mb_cavlc() failed due to wrong sl->qscale values,
e.g. dquant out of range, set the qscale to be a valid value before
returning -1 and exiting the function. The qscale value can be used
later e.g. in loop filter.

This prevents storing the contents of CodecPrivate into extradata for
a codec that doesn't need nor expect any. It will among other things
