[XFS] use inode_change_ok for setattr permission checking

Instead of implementing our own checks use inode_change_ok to check for
necessary permission in setattr.  There is a slight change in behaviour
as inode_change_ok doesn't allow i_mode updates to add the suid or sgid
without superuser privilegues while the old XFS code just stripped away
those bits from the file mode.
