Fix a couple of bugs with wal_log_hints. 1. Replay of the WAL record for setting a bit in the visibility map contained an assertion that a full-page image of that record type can only occur with checksums enabled. But it can also happen with wal_log_hints, so remove the assertion. Unlike checksums, wal_log_hints can be changed on the fly, so it would be complicated to figure out if it was enabled at the time that the WAL record was generated.
2. wal_log_hints has the same effect on the locking needed to read the LSN of a page as data checksums. BufferGetLSNAtomic() didn't get the memo. Backpatch to 9.4, where wal_log_hints was added.
