That's definitely where the error was made visible, but commit 421221234ada ("KVM:
x86: Open code necessary bits of kvm_lapic_set_base() at vCPU RESET") is the real
culprit.  I'll send a patch later today.  I'm leaning toward a partial revert with
some extra comments.

Thanks for the debug!  I was having trouble reproducing the syzbot report.
