Add some more __noreturn annotations.

Many of these have been flushed out by kernel IBT support which made
objtool vmlinux validation much more common.

These annotations are generally a good thing as they improve readability
and code generation.

  x86/hyperv: Mark hv_ghcb_terminate() as noreturn
