Fix sporadic failure for MTR test galera_sr.GCF-1018B. The test sometimes fails due to an error that is logged to the error log unnecessarily. A deterministic test case (included in this patch) shows that the error is loggen when a transaction is BF aborted right before it opens the streaming log table to perform fragment removal. When that happens, the attempt to open the table fails and consequently an error is logged. There is no need to log this error, as an ER_LOCK_DEADLOCK error is returned to the client.
