offscreen rendering not working on lima-18.3
Commit a8606905 lima: use u_pipe_screen_get_param_defaults helper seems to have changed things so that offscreen rendering doesn't work on top of lima-18.3.
gbm-surface and the modified examples I use from https://github.com/enunes/mesa-test-programs no longer work.
It works fine on lima-18.2 and on lima-18.3 reverting a8606905.
