Modified Files:
        src/sys/ufs/ffs: ffs_vfsops.c

Log Message:
Currently, in ffs_reload(), we don't handle the possibility that the
superblock location may have changed. But that implies that we don't
handle the possibility that its size may have changed either.

Therefore: add a check to ensure the size hasn't changed. Otherwise the
mismatch leads to a memory corruption with kmem.
