Marek Szyprowski 3eec42a17a dma-mapping: avoid potential unused data compilation warning ...

[ Upstream commit c9b19ea630 ]

When CONFIG_NEED_DMA_MAP_STATE is not defined, dma-mapping clients might
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.
