Yan, Like 93ed2af165 hv: passthru TSC_ADJUST to VM with lapic pt
Linux access TSC_ADJUST to verify it has not tampered every time when enter idle.
So for RTVM running rt-linux, the access will cause vm exit which affect real-time performance.

This commit pass through TSC_ADJUST to VM with lapic_pt, to avoid TSC_ADJUST caused vm_exit.
For other VMs, TSC_ADJUST msr access is still trapped and emulated.
