avcodec/mlpdec: reset lossless crc checking when stream ends
Fixes invalid reports of bad lossless crc.
While here make end of stream message into debug level as it is
not really important to user.
Also wait for new major sync frame as invalid concating of files
may produce invalid files, which cause various errors.
