libglusterfs/src/iobuf.c: don't forget to unlock a mutex
commit ed83a4ee7b73e6b04694d1ac11ed25d2983ac943 changed locking order and forgot to unlock in a negative path (when index was -1). Coverity caught it (thanks!) as CID 1396581: Program hangs (LOCK) Note: I'm unlocking before logging the failure. I think it's the right order - logging can take a while (especially if your disk is slow). Compile-tested only! updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com> Change-Id: I82ac241edf1d511bf6807cf9c46c538ab9f4acc4
