KVM: s390: Use srcu in kvm_arch_vcpu_unlocked_ioctl()

Browse source

kvm_arch_vcpu_unlocked_ioctl() is called without further locks held, but
kvm_s390_inject_vcpu(), which is called from there, needs either the
kvm->srcu or the slots lock.

Fix by taking the kvm->srcu in kvm_arch_vcpu_unlocked_ioctl().
