iommu/tegra241-cmdqv: Fix -Wformat-truncation warnings in lvcmdq_error_header

Kernel test robot reported a few trucation warnings at the snprintf:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:
	In function ‘tegra241_vintf_free_lvcmdq’:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:56:
	warning: ‘%u’ directive output may be truncated writing between 1 and
	5 bytes into a region of size between 3 and 11 [-Wformat-truncation=]
  239 |         snprintf(header, hlen, "VINTF%u: VCMDQ%u/LVCMDQ%u: ",
      |                                                        ^~
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:32: note: directive argument
	in the range [0, 65535]
  239 |         snprintf(header, hlen, "VINTF%u: VCMDQ%u/LVCMDQ%u: ",
      |                                ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:239:9: note: ‘snprintf’ output
	between 25 and 37 bytes into a destination of size 32
  239 |         snprintf(header, hlen, "VINTF%u: VCMDQ%u/LVCMDQ%u: ",
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  240 |                  vcmdq->vintf->idx, vcmdq->idx, vcmdq->lidx);

Fix by bumping up the size of the header to hold more characters.
