iommu/dma: Fix incorrect error return on iommu deferred attach
scsi_dma_map() was reporting a failure during boot on an AMD machine
with the IOMMU enabled.
scsi_dma_map failed: request for 36 bytes!
The issue was tracked down to a mistake in logic: should not return
an error if iommu_deferred_attach() returns zero.
