KVM: ARM/arm64: fix broken __percpu annotation
commit 4000be423cb01a8d09de878bb8184511c49d4238 upstream.
Running sparse results in a bunch of noisy address space mismatches
thanks to the broken __percpu annotation on kvm_get_running_vcpus.
This function returns a pcpu pointer to a pointer, not a pointer to a
pcpu pointer. This patch fixes the annotation, which kills the warnings
from sparse.
