iommu/arm-smmu: Fix broken ATOS check

Commit 04a38d9cb0d5 ("iommu/arm-smmu: fix ARM_SMMU_FEAT_TRANS_OPS
condition") accidentally negated the ID0_ATOSNS predicate in the ATOS
feature check, causing the driver to attempt ATOS requests on SMMUv2
hardware without the ATOS feature implemented.

This patch restores the predicate to the correct value.
