iommu/tegra241-cmdqv: Fix unused variable warning
While testing some io-pgtable changes, I ran into a compiler warning
from the Tegra CMDQ driver:
drivers/iommu/arm/arm-smmu-v3/tegra241-cmdqv.c:803:23: warning: unused variable 'cmdqv_debugfs_dir' [-Wunused-variable]
803 | static struct dentry *cmdqv_debugfs_dir;
| ^~~~~~~~~~~~~~~~~
1 warning generated.
Guard the variable declaration with CONFIG_IOMMU_DEBUGFS to silence the
warning.
