iommu: Clean up release_device checks
Since .release_device is now called through per-device ops, any call
which gets as far as a driver definitely *is* for that driver, for a
device which has successfully passed .probe_device, so all the checks to
that effect are now redundant and can be removed. In the same vein we
can also skip freeing fwspecs which are now managed by core code.
