Fix a (fairly) long standing NULL pointer dereference if VM allocation fails, and do a bit of clean up on top. I would have preferred to omit patch 01, i.e. fix the bug via patch 02, but unfortunately (long term support) kernel 4.19 doesn't have the accounting changes, which would make backporting the fix extra annoying for no real benefit.
