drm/ttm: Fix an invalid freeing on already freed page in error path
If caching mode change fails due to, for example, OOM we
free the allocated pages in a two-step process. First the pages
for which the caching change has already succeeded. Secondly
the pages for which a caching change did not succeed.
However the second step was incorrectly freeing the pages already
freed in the first step.
Fix.
