[PATCH 9/9] treewide: Inline ib_dma_map_*() functions

[Bart Van Assche]

Almost all changes in this patch except the removal of local variables
that became superfluous and the actual removal of the ib_dma_map_*()
functions have been generated as follows:

git grep -lE 'ib_(sg_|)dma_' |
  xargs -d\\n \
    sed -i -e 's/\([^[:alnum:]_]\)ib_dma_\([^(]*\)(\&\([^,]\+\),/\1dma_\2(\3.dma_device,/g' \
           -e 's/\([^[:alnum:]_]\)ib_dma_\([^(]*\)(\([^,]\+\),/\1dma_\2(\3->dma_device,/g' \
	   -e 's/ib_sg_dma_\(len\|address\)(\([^,]\+\), /sg_dma_\1(/g'
