[PATCH v4 04/12] KVM: x86: Rename kvm_apic_has_events() to make it INIT/SIPI specific

[Sean Christopherson]

Rename kvm_apic_has_events() to kvm_apic_has_pending_init_or_sipi() so
that it's more obvious that "events" really just means "INIT or SIPI".

Opportunistically clean up a weirdly worded comment that referenced
kvm_apic_has_events() instead of kvm_apic_accept_events().

No functional change intended.
