Subject: [PATCH v4 17/17] perf: Drop guest callback (un)register stubs
Drop perf's stubs for (un)registering guest callbacks now that KVM
registration of callbacks is hidden behind GUEST_PERF_EVENTS=y. The only
other user is x86 XEN_PV, and x86 unconditionally selects PERF_EVENTS.
No functional change intended.
