KVM: PPC: Book3S PR: Turn on FP/VSX/VMX MSR bits in kvmppc_save_tm()
kvmppc_save_tm() invokes store_fp_state/store_vr_state(). So it is mandatory to turn on FP/VSX/VMX MSR bits for its execution, just like what kvmppc_restore_tm() did. Previously HV KVM has turned the bits on outside of function kvmppc_save_tm(). Now we include this bit change in kvmppc_save_tm() so that the logic is cleaner. And PR KVM can reuse it later.
