KVM: SVM: Drop superfluous "cache" of AVIC Physical ID entry pointer

Browse source

Drop the vCPU's pointer to its AVIC Physical ID entry, and simply index
the table directly.  Caching a pointer address is completely unnecessary
for performance, and while the field technically caches the result of the
pointer calculation, it's all too easy to misinterpret the name and think
that the field somehow caches the _data_ in the table.

No functional change intended.
