This commit fixes sporadic failures in galera_3nodes_sr.GCF-336 test. The following changes have been made here: 1) A small addition to the test itself which should make it more deterministic by waiting for non-primary state before COMMIT; 2) More careful handling of the wsrep_ready variable in the server code (it should always be protected with mutex). No additional tests are required.
