Subject: [PATCH] Remove sanity test in XRecOffIsValid.

Commit 061e7efb1b4c5b8a5d02122b7780531b8d5bf23d changed the rules
for splitting xlog records across pages, but neglected to update this
test.  It's possible that there's some better action here than just
removing the test completely, but this at least appears to get some
of the things that are currently broken (like initdb on MacOS X)
working again.
