sdfs is supposed to serialize entry fops by doing entrylk, but all the
locks are being done with all-zero lk-owner. In essence sdfs doesn't
achieve its goal of mutual exclusion when conflicting operations are
executed by same client because two locks on same entry with same
all-zero-owner will get locks. The patch which lead to sdfs-sanity.t
failure treats inodelk/entrylk/lk fops with all-zero lk-owner as Invalid
request to prevent these kinds of bugs. So it exposed the bug in sdfs. I
sent a fix for sdfs @ https://review.gluster.org/#/c/glusterfs/+/22582
