[PATCH] KVM: Fix GFP_KERNEL alloc in atomic section bug

[PATCH] KVM: Fix GFP_KERNEL alloc in atomic section bug

KVM does kmalloc() in an atomic section while having preemption disabled via
vcpu_load().  Fix this by moving the ->*_msr setup from the vcpu_setup method
to the vcpu_create method.

(This is also a small speedup for setting up a vcpu, which can in theory be
more frequent than the vcpu_create method).
