Another fix, this time in common IOMMU sysfs code
- In the conversion from the old iommu sysfs-code to the
iommu_device_register interface, I missed to update the
release path for the struct device associated with an IOMMU.
It freed the 'struct device', which was a pointer before, but
is now embedded in another struct. Freeing from the middle of
allocated memory had all kinds of nasty side effects when an
IOMMU was unplugged. Unfortunatly nobody unplugged and IOMMU
until now, so this was not discovered earlier. The fix is to
make the 'struct device' a pointer again.
