drm/ttm: Make sure BOs being swapped out are cacheable

commit 239ac65fa5ffab71adf66e642750f940e7241d99 upstream.

The current caching state may not be tt_cached, even though the
placement contains TTM_PL_FLAG_CACHED, because placement can contain
multiple caching flags. Trying to swap out such a BO would trip up the

	BUG_ON(ttm->caching_state != tt_cached);

in ttm_tt_swapout.
