BUG/MINOR: hlua: add check for lua_newstate

Calling lual_newstate(Init main lua stack) in the hlua_init_state()
function, the return value of lua_newstate() may be NULL (for example
in case of OOM). In this case, L will be NULL, and then crash happens
in lua_getextraspace(). So, we add a check for lua_newstate.

This should be backported at least to 2.4, maybe further.
