Avoid WAL flush checks for unlogged buffers in GetVictimBuffer() GetVictimBuffer() rejects a victim buffer if it is from a bulkread strategy ring and reusing it would require flushing WAL. Unlogged table buffers can have fake LSNs (e.g. unlogged GiST pages) and calling XLogNeedsFlush() on a fake LSN is meaningless.
This is a bit of future-proofing because currently the bulkread strategy is not used for relations with fake LSNs.
