st/dri: check pipe_screen->resource_get_handle() return value
Change dri2_query_image to check the return value of resource_get_handle
and return GL_FALSE if an error occurs.
For reference this is an example callstack that should propagate the
error back to the user:
i915_drm_buffer_get_handle
i915_texture_get_handle
u_resource_get_handle_vtbl
dri2_query_image
gbm_dri_bo_get_fd
gbm_bo_get_fd
