Potential use of uninitialized value in luaL_loadfilex from lauxlib.c

[Павел Отчерцов <pavel.otchertsov@...>]

In function luaL_loadfilex from lauxlib.c:

`LoadF lf;` is defined, and `lf.n` is used below without prior initialization.

I think at least there should be `lf.n = 0;` after the `lf` declaration.
