Subject: [PATCH MANUALSEL 5.15 9/9] x86/kvm: remove unused ack_notifier callbacks

From: Juergen Gross <jgross@...e.com>

[ Upstream commit 9dba4d24cbb5524dd39ab1e08886373b17f07ff2 ]

Commit f52447261bc8c2 ("KVM: irq ack notification") introduced an
ack_notifier() callback in struct kvm_pic and in struct kvm_ioapic
without using them anywhere. Remove those callbacks again.
