Fix MJPEG decoder for AMV files.
...
Since decoding is doing from the end and aligned by 16
previous code worked correctly only when picture height was dividable by 16,
otherwise it provides garbage in top lines and truncates bottom.
New code adjusts data[] pointers taking in account alignment issue.

Mans Rullgard. Value at the right side is 16 bit length signed.
We can not know for sure that short is in fact 16 bits, even if
this virtually always is the case.
