Do compatibility checks when enabling hardware to effectively add
compatibility checks when onlining a CPU.  Abort enabling, i.e. the
online process, if the (hotplugged) CPU is incompatible with the known
good setup.

This paragraph is not true with this patch being before "KVM: Rename andmove CPUHP_AP_KVM_STARTING to ONLINE section".
