quick-read: Discard cache for fallocate, zerofill and discard ops
The fallocate, zerofill and discard modify file data on the server thus rendering stale any cache held by the xlator on the client. BUG: 1524252 Change-Id: I432146c6390a0cd5869420c373f598da43915f3f Signed-off-by: Sachin Prabhu <sprabhu@redhat.com>
