VT-d/ATS: misc fixes

First of all there were three places potentially de-referencing NULL
(two after an allocation failure, and one after a failed lookup).

Second, if ATS_ENABLE was already set, the device would not have got
added to the ats_devices list, potentially resulting in
dev_invalidate_iotlb() doing an incomplete job.
