xfs: switch to NOFS allocation under i_lock in xfs_dir_cilookup_result 



xfs_dir_cilookup_result is always called with i_lock held, but i_lock is taken
in reclaim context so all allocations under it must avoid recursions into the
filesystem.

Reported by the new reclaim context tracing in lockdep.
