s390 maintainers: is the ability to send a NMI to a specific CPU
really used in s390? The only way to use it today is to use HMP,
so I guess no management interface really supports it.

s390-ccw is the only machine that uses the cpu_index parameter.
If we remove it, it will allow us to simplify the code.
Otherwise, we will need to extend the inject-nmi command to
accept a "cpu" parameter.
