[PATCH 2/2] cpu: Assert a vCPU is created before resetting it

[Philippe Mathieu-Daudé]

cpu_reset() might modify architecture-specific fields allocated
by qemu_init_vcpu(). To avoid bugs similar to the one fixed in
commit 00d0f7cb66 when introducing new architectures, assert a
vCPU is created before resetting it.
