x86/events/amd/iommu: Increase IOMMU_NAME_SIZE
The init_one_iommu() takes an unsigned int argument that can't be checked for
the boundaries at compile time and GCC complains about that when build with
`make W=1`:
arch/x86/events/amd/iommu.c:441:53: note: directive argument in the range [0, 4294967294]
arch/x86/events/amd/iommu.c:441:9: note: ‘snprintf’ output between 12 and 21 bytes into a destination of size 16
Increase the size to cover all possible cases.
