KVM: x86: Expose several TSC helpers via x86.h for use by MSR code

Browse source

Begrudgingly move adjust_tsc_offset_{guest,host}() to x86.h as inlines,
and expose several other TSC helpers in anticipation of moving KVM's MSR
code to a dedicated msrs.c.  Unfortunately for KVM, several MSRs that KVM
emulates can affect TSC state.

Opportunistically drop a superfluous local "tsc_offset" variable, whose
existence causes checkpatch to complain about lack of a blank line.

No functional change intended.
