KVM: VMX: Remove scratch 'cpu' variable that shadows an identical scratch var

 From: Peng Hao <flyingpeng@tencent.com>

 Remove a redundant 'cpu' declaration from inside an if-statement that
 that shadows an identical declaration at function scope.  Both variables
 are used as scratch variables in for_each_*_cpu() loops, thus there's no
 harm in sharing a variable.
