swrast: Don't try to adjust_colors for <8bpc when handling R16, RG1616.
The GL_RED and GL_RG were tricking this code into executing, but it's
totally unprepared for a 16-bit channel and just rescaled the values
down to 0. We don't have anything with <8bit channels alongside >8bit
channels, so disabling it should be safe.
