On a second thought, no I don't have to: the request routine will try to
load any new microcode but if it fails, ->apply_microcode later simply
won't find it in the cache. And that's perfectly fine.
setup_online_cpu() still needs to run on each CPU unconditionally,
though, in order to setup the sysfs groups.
Thx.
