MINOR: lua-thread: hlua_ctx_renew() is never called with main gL lua state

The goal is no longer using "struct hlua" with global main lua_state.

if somewhere in the code, hlua_ctx_renew() is called with a global Lua
context, we have a serious bug. A crash is better than working with
this bug, so this patch remove a useless control.

In other way, this control were used during hlua_post_init() function.
The function hlua_post_init() used a call to the runtime hlua_ctx_resume()
function. This call no longer exists.
