    wslua: don't crash if disable_lua = true in init.lua
    
    in wslua_init(), our lua instance L is set to NULL if
    disable_lua is true in init.lua
    make sure that we leave wslua_init() in this case
    
    if we don't, we crash in lua_pop(L,1); with L==NULL
    
    Program received signal SIGSEGV, Segmentation fault.
