ARM: KVM: fix unbalanced get_cpu() in access_dcsw In the very unlikely event where a guest would be foolish enough to *read* from a write-only cache maintainance register, we end up with preemption disabled, due to a misplaced get_cpu(). Just move the "is_write" test outside of the critical section.
