KVM: nSVM: Use the "outer" helper for writing multiplier to MSR_AMD64_TSC_RATIO
When emulating nested SVM transitions, use the outer helper for writing
the TSC multiplier for L2. Using the inner helper only for one-off cases,
i.e. for paths where KVM is NOT emulating or modifying vCPU state, will
allow for multiple cleanups:
- Explicitly disabling preemption only in the outer helper
- Getting the multiplier from the vCPU field in the outer helper
- Skipping the WRMSR in the outer helper if guest state isn't loaded
Opportunistically delete an extra newline.
No functional change intended.
