Subject: [PATCH] Fix copy & paste mistake in pg_get_replication_slots().

XLogRecPtr was compared with InvalidTransactionId instead of
InvalidXLogRecPtr. As both are defined to the same value this doesn't
cause any actual problems, but it's still wrong.

Backpatch: 9.4-master, bug was introduced in 9.4
