This patch modifies xfs_attr_item to store a xfs_da_args, a xfs_buf pointer
and a new state type. We will use these in the next patch when
we modify xfs_set_attr_args to roll transactions by returning EAGAIN.
Because the subroutines of this function modify the contents of these
structures, we need to find a place to store them where they remain
instantiated across multiple calls to xfs_set_attr_args.
