Michael Niedermayer f1c21a200b avformat/mvdec: Check size in read_table() for validity ...

This check is redundant with the previous commit but it provides
better error messages and feedback while the previous commit
ensures that var_read_string() doesnt return uninitialized arrays
if it itself is feeded with an invalid size possibly through a
different future codepath.
