[Tarantool-patches] [PATCH luajit 14/19] Fix debug.getinfo() argument check.

[Sergey Kaplun]

From: Mike Pall <mike>

Thanks to Sergey Ostanevich.

(cherry-picked from commit 0cd643d7cfc21bc8b6153d42b86a71d557270988)

This patch just reverts the commit
48f463e613db6264bfa9acb581fe1ca702ea38eb ("luajit: fox for
debug.getinfo(1,'>S')") and applies the one from the main repo for the
consistency with the upstream.
