libglusterfs: fix glusterd statedump crash
commit 3c04a91 removed setting typeStr to NULL if num_allocs is set to 0, this has caused this regression. Code has been put back like earlier and to avoid statedump printing all the NULL values check is modified to see skip the records if num_allocs is 0 instead of total_allocs Change-Id: Ib8bcc2fba908e88cf52b641c3f6bcba74f5e667c BUG: 1359190 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/14987 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: N Balachandran <nbalacha@redhat.com> Reviewed-by: Prashanth Pai <ppai@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>
