st/dri: check pipe_screen->resource_get_handle() return value

Browse source 
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
