xfs: Add helper function xfs_attr_try_sf_addname
commit 4c74a56b9de76bb6b581274b76b52535ad77c2a7 upstream.
This patch adds a subroutine xfs_attr_try_sf_addname
used by xfs_attr_set. This subrotine will attempt to
add the attribute name specified in args in shortform,
as well and perform error handling previously done in
xfs_attr_set.
This patch helps to pre-simplify xfs_attr_set for reviewing
purposes and reduce indentation. New function will be added
in the next patch.
[dgc: moved commit to helper function, too.]
