dma-mapping: avoid potential unused data compilation warning

Browse source

[ Upstream commit c9b19ea630 ]

report unused data compilation warnings for dma_unmap_*() calls
arguments. Redefine macros for those calls to let compiler to notice that
it is okay when the provided arguments are not used.
