Add mayfail bool parameter to module loading functions. 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.
