Revert "drm/ttm: check null pointer before accessing when swapping"

Browse Source 
This reverts commit d39971d902 which is
commit 2dedcf414b upstream.

It breaks the Android kernel abi, and is not needed for any Android
devices at this time.  If it is needed in the future, it can be brought
back in an abi-safe way.
