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.
