Thadeu Lima de Souza Cascardo 91d7e9df42 drm/ttm: Fix bo resource use-after-free 
When allocating a lot of buffers and putting the TTM under memory pressure,
during swapout, it might crash the system with the stack trace below.

It turns out that ttm_bo_swapout_cb might replace bo->resource when it
moves it to system cached.

When commit c06da4b357 ("drm/ttm: Tidy usage of local variables a little
bit") used a local variable for bo->resource, it used the freed resource
later in the function, leading to a UAF.

Move back to using bo->resource in all cases in that function instead of a
local variable.
