client_t: Fix memory leaks
- Assign frame->root->client so that gf_client_unref happens in server_connection_cleanup_flush_cbk - Avoid taking extra ref in gf_client_get TODO: The whole reason why there are two types of refs bind, ref-count is to avoid lock inside lock which is not the case now. I will be sending one more patch which will accomplish that as well as changing the tablearray to list Change-Id: Ic9971cf248c5ee2cdbfdef8e9ff6d54e3ec60ced BUG: 1116672 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/8247 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
