KVM: VMX: clean up pi_wakeup_handler
Passing per_cpu() to list_for_each_entry() causes the macro to be
evaluated N+1 times for N sleeping vCPUs. This is a very small
inefficiency, and the code is cleaner if the address of the per-CPU
variable is loaded earlier. Do this for both the list and the spinlock.
