Fix memory leak on DSM slot exhaustion. If we attempt to create a DSM segment when no slots are available, we should return the memory to the operating system. Previously we did that if the DSM_CREATE_NULL_IF_MAXSEGMENTS flag was passed in, but we didn't do it if an error was raised. Repair.
Back-patch to 9.4, where DSM segments arrived.
