mesa: fix vertex format/attribute bug

If the tnl output attributes matches the swsetup input attributes we still
need to check if the desired vertex color type (float vs. chan) has changed
so that we use the right emit functions.

Fixes a conformance failure found with logicop test at pathlevel 3.
