Subject: [PATCH] drm/nouveau: sgdma: add comment around suspiscious error
 handler

Common programming sense dictates that resources allocated by a function
are freed by this function should it fails, but this is not the case for
the allocated structure of nouveau_sgdma_create_ttm(). It seems that
n00b contributors attempt to fix this one like bugs flying towards a bug
zapper, so add a comment to hopefully prevent this from happening
anymore.
