mesa: Move buffers-unmapped earlier in check_valid_to_render().

This needs to be above the switch on API, as that can return true
(valid to render) before this error check even had a chance to run.

Fixes ESEXT-CTS.draw_elements_base_vertex_tests.invalid_mapped_bos,
which worked before commit 72f1566f90c434c7752d8405193eec68d6743246.
