[m2vd_parser]: fix wrong frame period cause PTS predict error

Browse Source 
When the frame period changes, it will be recorded in the last frame
period first, but this value is an error value, which cannot be updated
back to the correct frame period later, so the correct frame period
should be restored at this time.
