s3: Optimize g_lock_lock for a heavily contended case
Only check the existence of the lock owner in g_lock_parse, check the rest of
the records only when we got the lock successfully. This reduces the load on
process_exists which can involve a network roundtrip in the clustered case.
(cherry picked from commit 07978bd175395e0dc770f68fff5b8bd8b0fdeb51)
