I changed back to using GetUserId() for the call to check_enable_rls()
at those three call sites, and added to the comments to explain why.

While looking at ri_ReportViolation() I spotted what I believe to be a
bug in the current logic -- namely, has_perm is initialized to true,
and when check_enable_rls() returns RLS_ENABLED we never reset
has_perm to false, and thus leak info even though the comments claim
we don't. I fixed that here, but someone please take a look and
confirm I am reading that correctly.

Beyond that, any additional comments?

Thanks,

Joe
