cluster/dht: Fix crash in "nuke-dir" feature
My patch at https://review.gluster.org/16419 is resulting
in core dumps everytime I run tests/features/nuke.t.
Turns out dht, upon successfully "nuking" a directory,
which was initiated through a setxattr, unwinds the operation
with rmdir fop signature, resulting in readdir-ahead casting
a struct iatt (preparent) to dict_t, leading to a crash.
