fbdev: Fix logo if logo depth is less than framebuffer depth
The VGA16 logo (bpp = 4) and monochrome logo (bpp = 1) do not contain any color information (no CLUT). If the fb depth is > logo depth, these logo's will not properly display. Fix by using the console palette instead of creating a new one.
