[PATCH 2/2] drm/udl: Use iosys_map getter for virtual address

[oushixiong1025]

From: Shixiong Ou <oushixiong@xxxxxxxxxx>

Replace direct access to map->vaddr with the new iosys_map_get_vaddr()
helper function. This properly uses the iosys_map abstraction layer
instead of directly accessing structure members.
