iommu/amd: Print reason for iommu_map_page failure in map_sg
Since there are multiple possible failures in iommu_map_page it would be useful to know which case is being hit when the error message is printed in map_sg. While here, fix up checkpatch complaint about using function name in a string instead of __func__.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
