Add note about CreateStatistics()'s selective use of check_rights.

Commit 5e4fcbe531 added a check_rights parameter to this function
for use by ALTER TABLE commands that re-create statistics objects.
However, we intentionally ignore check_rights when verifying
relation ownership because this function's lookup could return a
different answer than the caller's.  This commit adds a note to
this effect so that we remember it down the road.
