fix MSR_COUNT for kvm_arch_save_regs()
A new register was added to the load/save list on commit
d283d5a65a2bdcc570065267be21848bd6fe3d78, but MSR_COUNT was not updated, leading
to potential stack corruption on kvm_arch_save_regs().
The following registers are saved by kvm_arch_save_regs():
1) MSR_IA32_SYSENTER_CS
2) MSR_IA32_SYSENTER_ESP
3) MSR_IA32_SYSENTER_EIP
4) MSR_STAR
5) MSR_IA32_TSC
6) MSR_VM_HSAVE_PA
7) MSR_CSTAR (x86_64 only)
8) MSR_KERNELGSBASE (x86_64 only)
9) MSR_FMASK (x86_64 only)
10) MSR_LSTAR (x86_64 only)
