vfio: Remove reports of DMA mapping errors in backends
Currently, the mapping handlers of the IOMMU backends, VFIO IOMMU Type 1 aka. legacy and IOMMUFD, return an errno and also report an error. This can lead to excessive log messages at runtime for recurring DMA mapping errors. Since these errors are already reported by the callers in the vfio_container_dma_un/map() routines, simply remove them and allow the callers to handle the reporting. The mapping handler of the IOMMUFD backend has a comment suggesting MMIO region mapping failures return EFAULT. I am not sure this is entirely true, so keep the EFAULT case until the conditions are clarified.
