This fixes "margin colour" (colour used to clear margins - e.g. a half of line
at the bottom of 100x37 console on 800x600 framebuffer).

I don't know what was the intention behind using attr_bgcol_ec() here, but it
caused using of background colour of last erase character to clear margins -
which definitely isn't what we want...
This patch changes margin colour to black (or colour 0 in palette modes).
