RH-Commit: [3/115] ef00896ed2cac6bc1ef39f21aad422ae5b571cb6 (bonzini/rhel-qemu-kvm)

kvm_filer_msr() is only used from i386 kvm module. Make it static so that its
easy for developers to understand that its not used anywhere else.
Same for QEMURDMSRHandler, QEMUWRMSRHandler and KVMMSRHandlers definitions.
