s3: Avoid a thundering herd in g_lock_unlock

Only notify the first 5 pending lock waiters. This avoids a thundering herd
problem that is really nasty in a cluster. It also makes acquiring a lock a bit
more FIFO, lock waiters are added to the end of the array.
(cherry picked from commit 725b3654f831fbe0388cc09f46269903c9eef1d7)
