While verifying that the swiotlb high water marks are never used
if CONFIG_DEBUG_FS is unset, I guarded the corresponding fields
in strut io_tlb_mem with an #ifdef, but then I ran into a build
failure. This patch tries to clean up the optional debugfs code
in swiotlb.

The patch should be applied to the dma-mapping for-next tree.

  swiotlb: Omit total_used and used_hiwater if !CONFIG_DEBUG_FS
