Doc: undo mistaken adjustment to LOCK TABLE docs in back branches.
Commits 59ab4ac32 et al mistakenly copied-and-pasted some text about
how LOCK on a view recurses to referenced tables into pre-v11 branches,
which in fact don't do that. Undo that, and instead state clearly
that they don't. (I also chose to add a note that this behavior
changed in v11. We usually don't back-patch such statements, but
since it's easy to add the warning now, might as well.)
Noted while considering followup fixes for bug #16703.
