dma-mapping: avoid potential unused data compilation warning
[ Upstream commit c9b19ea63036fc537a69265acea1b18dabd1cbd3 ]
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.
