KVM: x86: Add support for save/load MSR_SMI_COUNT
This MSR returns the number of #SMIs that occurred on
CPU since boot.
KVM commit 52797bf9a875 ("KVM: x86: Add emulation of MSR_SMI_COUNT")
introduced support for emulating this MSR.
This commit adds support for QEMU to save/load this
MSR for migration purposes.
