osmesa: fix broken triangle/line drawing when using float color buffer
Doesn't seem to help with bug 71363 but it fixed a failure I found in my testing. Cc: "9.2" <mesa-stable@lists.freedesktop.org> Cc: "10.0" <mesa-stable@lists.freedesktop.org> (cherry picked from commit a66a008b17872f3eab91b7d04dd70e4537bdb627)
