David Herrmann aed2c03c8d drm/gem: fix mmap vma size calculations
The VMA manager is page-size based so drm_vma_node_size() returns the size
in pages. However, drm_gem_mmap_obj() requires the size in bytes. Apply
PAGE_SHIFT so we no longer get EINVAL during mmaps due to too small
buffers.

This bug was introduced in commit:

  "drm/gem: convert to new unified vma manager"
