Fix memory leak in LogStandbySnapshot(). The array allocated by GetRunningTransactionLocks() needs to be pfree'd when we're done with it. Otherwise we leak some memory during each checkpoint, if wal_level = hot_standby. This manifests as memory bloat in the checkpointer process, or in bgwriter in versions before we made the checkpointer separate.
Reported and fixed by Naoya Anzai. Back-patch to 9.0 where the issue was introduced. In passing, improve comments for GetRunningTransactionLocks(), and add an Assert that we didn't overrun the palloc'd array.
