dri: Fix hardware cursor for cards without modifier support

Browse Source 
After the breaking commit, gbm_bo_create_with_modifiers({LINEAR}) returns
a BO with gbm_bo_get_modifier() = INVALID. This restores the functionality
and fixes most notably, hardware cursors for cards without modifiers.

Fixes #12039.
