mesa/st: fix color outputs in presence of sample mask output

Browse Source 
Commit c5d822dad9 added support for sample mask incorrectly. It became
treated as a color output, and messed up the color output indices.
Revert the hunk that did that, and add explicit support just like for
depth/stencil writes.
