iommu: Use sysfs_emit() for sysfs show

Use sysfs_emit() instead of the sprintf() for sysfs entries. sysfs_emit()
knows the maximum of the temporary buffer used for outputting sysfs
content and avoids overrunning the buffer length.

Prefer 'long long' over 'long long int' as suggested by checkpatch.pl.
