iommu/vt-d: Increase buffer size for device name

GCC is not happy with the current code, e.g.:

.../iommu/intel/dmar.c:1063:9: note: ‘sprintf’ output between 6 and 15 bytes into a destination of size 13
 1063 |         sprintf(iommu->name, "dmar%d", iommu->seq_id);

When `make W=1` is supplied, this prevents kernel building. Fix it by
increasing the buffer size for device name and use sizeoF() instead of
hard coded constants.
