s)used to properly
free the (over)allocated scatterlist.
This patch only fixes the sg_table->nents entries in the sg_table objects
exported by the dmabuf related functions, so the other drivers, which
might share buffers with i915 could rely on the nents and orig_nents
values.

Changes since v1:
- Added the missing tegra driver (noticed by kbuild robot)
- Rebased off of drm-intel-next to get the i915 selftest that is new
- Fixed nits Sinclair pointed out.
drivers/dma-buf/dma-buf.c
were using unsigned long locally
with the lower_32_bits annotation to make it explicitly
clear what is happening.
