V4L/DVB: v4l videobuf: add videobuf_buffer *buf as argument to mmap_mapper
mmap_mapper should operate on a buffer, not on a complete queue. So let the videobuf-core find the correct buffer instead of duplicating that code in each mmap_mapper implementation. The dma-sg implementation has backwards compatibility code for handling the V4L1_COMPAT layer. This code is now under the v4L1_COMPAT config option.
