iommu/amd: Fix bug in put_pasid_state_wait
This patch fixes a bug in put_pasid_state_wait that appeared in kernel 4.0
The bug is that pasid_state->count wasn't decremented before entering the
wait_event. Thus, the condition in wait_event will never be true.
The fix is to decrement (atomically) the pasid_state->count before the
wait_event.
