cluster/dht: Fixed double UNWIND in lookup everywhere code
In dht_lookup_everywhere_done: Line: 1194 we call DHT_STACK_UNWIND and in the same if condition we go ahead and call, goto unwind_hashed_and_cached; which at Line 1371 calls another UNWIND. As is obvious, higher frames could cleanup their locals and on receiving the next unwind could cause a coredump of the process. Fixed the same by calling the required return post the first unwind Change-Id: Ic5d57da98255b8616a65b4caaedabeba9144fd49 BUG: 1139812 Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: http://review.gluster.org/8666 Reviewed-by: N Balachandran <nbalacha@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: susant palai <spalai@redhat.com>
