leases: Fix the recall code path
1. Replace frame->op usage with frame->root->op, as frame->op is not filled with appropriate value in all cases 2. Add few log messages 3. Fix boolean assignment Change-Id: I340f2200c1fcc4f4ce5a139b0fd22508cb8ac1e3 BUG: 1319992 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/14434 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra Talur <rtalur@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
