mesa: move unrefs of array objects earlier in _mesa_free_context_data()

If a non-default array object was bound at context destruction time
we'd try to unreference the array object after it was already deleted
in _mesa_free_varray_data().  Now do the unref first.

Fixes a regression from commit 86f53e6d6bd07e2bc3ffcadeb9a4418fbae06e0b.
