iris: Use linear for exported resources if we can't convey tiling

Browse Source 
If we have modifiers, we can use those to convey the tiling of exported
resources.  If we have the deprecated i915 GET/SET_TILING uAPI, we can
use that to convey the tiling.

If we have neither, then we have to fall back to linear.

Fixes: e6588354360 ("iris/bufmgr: Do not use map_gtt or use set/get_tiling on DG1")
