[PATCH] qemu-kvm: Remove kvm_set_boot_cpu_id

[Jan Kiszka <jan.kiszka@xxxxxxxxxxx>]

Upstream just as well as qemu-kvm only support CPU 0 as boot CPU. And
that is also the KVM ABI default if the user does not issue any
KVM_SET_BOOT_CPU_ID.

So let's drop this redundancy. It can be re-introduced via upstream once
we support something more sophisticated.
