xfs: eliminate lockdep false positives in xfs_attr_shortform_list
xfs_attr_shortform_list() only called from a non-transactional context, it
hold ilock before alloc memory and maybe trapped in memory reclaim. Since
commit 204fae32d5f7("xfs: clean up remaining GFP_NOFS users") removed
GFP_NOFS flag, lockdep warning will be report as [1]. Eliminate lockdep
false positives by use __GFP_NOLOCKDEP to alloc memory
in xfs_attr_shortform_list().
