iris: fix PIPE_RESOURCE_PARAM_STRIDE for buffers

Browse source 
Iris calls iris_resource_get_param with PIPE_RESOURCE_PARAM_STRIDE
internally now when exporting memory objects. OpenCL's gl_sharing allows
to export buffers as well, which do not have strides.

This fixes the assert being hit there for buffers.
