    KVM: ppc: fix set regs to take care of msr change
    
    When changing some msr bits e.g. problem state we need to take special
    care of that. We call the function in our mtmsr emulation (not needed for
    wrtee[i]), but we don't call kvmppc_set_msr if we change msr via set_regs
    ioctl.
    It's a corner case we never hit so far, but I assume it should be
    kvmppc_set_msr in our arch set regs function (I found it because it is also
    a corner case when using pv support which would miss the update otherwise).
