cleanup a fix and add the vma_set_file function

by Christian König

Hi Andrew, can I get you Acked-by to merge this cleanup through the drm-misc-next branch? The affected drivers are mostly from the DRM subsystem. The fix for the other problem you pointed out in mmap_region() has already shown up in that branch. Thanks in advance, Christian.
