  x86/hyperv: Protect set_hv_tscchange_cb() against getting preempted (2021-10-28 11:59:13 +0000)

There are two merges from the tip tree: one is because of Tianyu's
patches went in via tip/x86/sev, the other is because a tree-wide
cleanup in tip/x86/cc conflicted with Tianyu's patch.

Instead of requiring you to fix up I thought I'd just do it myself.

Thanks,
Wei.
