The microcode loader now uses the stop-machine facility for NMI-based
loading. The offline handler is the only remaining user of the microcode
NMI static key.

But the handler already has internal guarding. Offline CPU doesn't matter
how fast it handles anyway, so remove the static key. Instead, check the
build option.
