[PATCH v5 3/3] drm/udl: use DRM_GEM_SHMEM_DRIVER_OPS_NO_MAP_SGT

[oushixiong1025 at 163.com]

From: Shixiong Ou <oushixiong at kylinos.cn>

Import dmabuf without mapping its sg_table to avoid issues likes:
   udl 2-1.4:1.0: swiotlb buffer is full (sz: 2097152 bytes), total 65536 (slots), used 1 (slots)
