Revert "BUILD: lua: silence some compiler warnings about potential null derefs"

This reverts commit f1ffb39b614b0d9654c9450ac6e8c88cfc942784.

It breaks Lua causing some timeouts. Removing the __unreachable() statement
from WILL_LJMP() fixes it. It's very strange and unclear whether it's an
issue with WILL_LJMP() not fullfilling its promise of not returning, if
the code emitted with __unreachable() gets broken, or anything else. Let's
revert this for now.
