Revert "intel: Add some defense against buffer allocation failure for subimage blits"

This reverts commit de7678ef521f4fb34459e407a66ab8bf8be733e1.

The conversion from using drm_intel_bo_alloc_tiled to a plain
drm_intel_bo_alloc forgot that the tiled variant adjusts the
allocation height even for TILING_NONE.
