KVM: s390: use yield instead of schedule to implement diag 0x44 

diag 0x44 is the common way on s390 to yield the cpu to the hypervisor.
It is called by the guest in cpu_relax and in the spinlock code to
yield to other guest cpus.

This semantic is similar to yield. Lets replace the call to schedule with
yield to make sure that current is really yielding.
