KVM: x86: Limit check IDs for KVM_SET_BOOT_CPU_ID
Do not accept IDs which are definitely invalid by limit checking the
passed value against KVM_MAX_VCPU_IDS and 'max_vcpu_ids' if it was
already set.
This ensures invalid values, especially on 64-bit systems, don't go
unnoticed and lead to a valid id by chance when truncated by the final
assignment.
