gallium/dri: fix dri2_from_planar for multiplanar images

Browse source 
Fix the gbm_dri_bo_get_handle_for_plane use case by allowing plane > 0
in dri2_from_planar for images with multiple planes in separate chained
texture resources.

Not all multiplanar resources are chained, though. The iris aux buffer
is a separate plane in the same resource.
