Log Message:
-----------
Fix bug in wasender's xlogid boundary handling, reported by Erik Rijkers.
LogwrtRqst.Write can be set to non-existent FF log segment, we mustn't
try to send that in XLogSend().
Also fix similar bug in ReadRecord(), which I just introduced in the
ReadRecord() refactoring patch.
