[PATCH 08/19] KVM: SVM: Remove redundant cluster calculation that also creates a shadow

[Sean Christopherson]

Drop the redundant "cluster" calculation and its horrific shadowing in
the x2avic logical mode path.  The "cluster" that is declared at an outer
scope is derived using the exact same calculation and has performed the
left-shift.

No functional change intended.
