Revert "For inplace update, send nontransactional invalidations."

This reverts commit 95c5acb3fc261067ab65ddc0b2dca8e162f09442 (v17) and
counterparts in each other non-master branch.  If released, that commit
would have caused a worst-in-years minor release regression, via
undetected LWLock self-deadlock.  This commit and its self-deadlock fix
warrant more bake time in the master branch.

Reported by Alexander Lakhin.
