KVM: s390: Fix vcpu_load handling in interrupt code
Recent changes (KVM: make processes waiting on vcpu mutex killable) now requires to check the return value of vcpu_load. This triggered a warning in s390 specific kvm code. Turns out that we can actually remove the put/load, since schedule will do the right thing via the preempt notifiers.
