cluster/dht: Del GF_READDIR_SKIP_DIRS key from dict for first_up
Currently, we sent GF_READDIR_SKIP_DIRS for all subvolumes if first_subvol != first_up_subvolume. Also first_up_subvolume can change with-in the life of a call and cbk. Saving the first_up_subvol in dht_local for checks. Back porting fix http://review.gluster.org/5577 BUG: 996474 Change-Id: I67b5bbe781e12812557b569b7d0a0beba4224159 Signed-off-by: shishir gowda <gowda.shishir@gmail.com> Reviewed-on: http://review.gluster.org/6468 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
