KVM: s390: remove superfluous save_fpu_regs() call
The save_fpu_regs() call in kvm_arch_vcpu_ioctl_get_fpu() is pointless: it
will save the current user space fpu context to the thread's save area. But
the code is accessing only the vcpu's save are / mapped register area,
which in this case are not the same.
Therefore remove the confusing call.
