From: Dave Chinner <dchinner@xxxxxxxxxx>
Now that xfs_attri_set_iter() has initial states for removing
attributes, switch the pure attribute removal code over to using it.
This requires attrs being removed to always be marked as INCOMPLETE
before we start the removal due to the fact we look up the attr to
remove again in xfs_attr_node_remove_attr().
Note: this drops the fillstate/refillstate optimisations from
the remove path that avoid having to look up the path again after
setting the incomplete flag and removeing remote attrs. Restoring
that optimisation to this path is future Dave's problem.
