Fix a bug which may cause infinite loop
When the condition is "status == FXCODEC_STATUS_DECODE_TOBECONTINUE"
while |status| never gets updated in the loop, it would enter infinite
loop.
Also, since Start_decode_MMR() never returns
FXCODEC_STATUS_DECODE_TOBECONTINUE, there is no point to check on the
return value for that.
