Thierry Reding 6f530e22fd drm/tegra: gem: Do not try to dereference ERR_PTR() 
[ Upstream commit cb7e1abc2c ]

When mapping the DMA-BUF attachment fails, map->sgt will be an ERR_PTR-
encoded error code and the cleanup code would try to free that memory,
which obviously would fail.

Zero out that pointer after extracting the error code when this happens
so that kfree() can do the right thing.
