jfs: Update agstart when resizing volume
A comment indicates that the IAG's agstart does not need to be updated since it will always point to a block in the same aggregate group, but jfs_fsck isn't so forgiving and reports it as an error. I'm fixing this in jfsutils as well, so either a new kernel or new utilities will be sufficient to fix the problem. Signed-off-by: Dave Kleikamp <dave.kleikamp@oracle.com>
