There is a test in tgafb_mono_imageblit() for a colour image with a
fall-back to cfb_imageblit(). The test is not necessary as the only
caller, which is tgafb_imageblit(), checks it too and only invokes this
function for monochrome images. It looks like a left-over from before
some changes to tgafb_imageblit().

Checked with checkpatch.pl and at the run time with an 8-bit TC frame
buffer on a MIPS host.
