KVM: x86: Rename inject_pending_events() to kvm_check_and_inject_events()

Browse source

Rename inject_pending_events() to kvm_check_and_inject_events() in order
to capture the fact that it handles more than just pending events, and to
(mostly) align with kvm_check_nested_events(), which omits the "inject"
for brevity.

Add a comment above kvm_check_and_inject_events() to provide a high-level
synopsis, and to document a virtualization hole (KVM erratum if you will)
that exists due to KVM not strictly tracking instruction boundaries with
respect to coincident instruction restarts and asynchronous events.

No functional change inteded.
