LinuxKPI: dma-mapping.h unify "mask" and "dma_mask"
In some places we are using "mask" and others "dma_mask" for the same thing. Harmonize the various places to "dma_mask" as used in linux_pci.c. For the declaration remove the argument names to avoid the entire problem. This is in preparation for an upcoming change. No functional changes intended.
