    eal: fix DMA mask validation with IOVA mode option
    
    When --iova-mode is explicitly specified in command line, DMA mask
    constraints were not being validated, leading to potential runtime
    failures when device DMA capabilities are exceeded.
    
    The issue occurred because rte_bus_get_iommu_class() was only called
    during IOVA mode auto-detection, but this function has the important
    side effect of triggering DMA mask detection (e.g., Intel IOMMU
    address width checking via pci_device_iommu_support_va()).
    
    This created an inconsistency, when choosing explicit mode,
    the DMA checks are bypassed, but when choosing auto-detection mode,
    the constraints are checked and enforced.
    
    The fix moves rte_bus_get_iommu_class() outside the conditional logic
    to ensure it's always called during EAL initialization.
