KVM: s390: Add missing srcu in kvm_s390_set_irq_state()

Browse Source 
Like kvm_s390_inject_vcpu(), kvm_s390_set_irq_state() also needs the
kvm->srcu or the slots lock when performing the Store status operation.

Fix by taking kvm->srcu in kvm_s390_set_irq_state().

Fixes: ba5c1e9b6c ("KVM: s390: interrupt subsystem, cpu timer, waitpsw")
Fixes: 062e44a931 ("KVM: s390: Use srcu in kvm_arch_vcpu_unlocked_ioctl()")
