Set it to true for module_load_qom_all() because device modules might not load into all system emulation variants. qemu-system-s390x for example will not load qxl because it lacks vga support. Makes "make check" less chatty. Drop module_loaded_qom_all check in module_load_qom_one to make sure we see errors for explicit load requests, i.e. module_load_qom_one("qxl") failing will log an error no matter whenever module_load_qom_all() was called before or not.
