Fix comment in xlogutils.c
The existing callers of XLogReadDetermineTimeline() performing recovery
need to check a replay LSN position when determining on which timeline
to read a WAL page. A portion of the comment describing this function
said exactly that, while referring to a routine for fetching a write
LSN, something not available in recovery.
