EX-7601 vvp: remove unaligned write restriction

This series will resolve the unaligned write issue for
compressed files, so we need to remove the restriction on
unaligned writes in order to test it.

This does not mean unaligned writes are working yet, but we
need to make this change so the subsequent patches can be
tested.
