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!
