    wslua: do not pop from empty stack on newer LUA versions
    
    Fixes this failure:
    
        tshark: lapi.c:175: lua_settop: Assertion `(-(idx+1) <= (L->top - (func + 1))) && "invalid new top"' failed.
    
    Found using LUA 5.2 compiled with -DLUA_USE_APICHECK. Note that the
    value returned by luaopen_bit does not affect the size of the stack
    after using lua_call; if there are excess return values, then these will
    be dropped after calling lua_call. See http://www.lua.org/pil/26.2.html
    
    I also verified that the stack is still empty after calling all
    wslua_reg_module functions.
