Using InvalidateBuffer is wrong, because if the page is concurrently dirtied, it will throw away the dirty page without calling smgwrite(). In Neon, that means that the last-written LSN update for the page is missed. In v16, use the new InvalidateVictimBuffer() function that does what we need. In v15 and v14, backport the InvalidateVictimBuffer() function. Fixes issue #7802
