Marc Zyngier 15bbc1b28f 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.
