[0/2] KVM: arm64: Fix DEMUX register access

Message

The first patch is a fix, but not one likely to ever truly be needed,
as it's unlikely to find seven levels of cache. The bug was found
while code reading. Writing the second patch was actually why I was
reading the code. The issue being fixed for the get-reg-list test was
found when running it on a different machine than what was used to
develop it.

Thanks,
drew
