Description of problem:

With
https://review.gluster.org/#/q/status:merged+project:glusterfs+branch:master+topic:ref-1568521
in, where fops that might decrement link count - such as UNLINK and RENAME -
rely on file link count before cleaning up shards, which is determined under
locks, it is important for LINK also to acquire locks to prevent
inconsistencies stemming from premature deletion of shards while the inode
continues to exist.
