KVM: x86: Add support for save/load MSR_SMI_COUNT

Browse source 
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.

Backports the relevant parts of commit e13713db5b609d9a83c9cfc8ba389d4215d4ba29 from qemu
