vt: fix background color on line feed, DEC invert
vt: fix background color on line feed, DEC invert

Original report: """I used to force my console to black-on-white by the
command `setterm -inversescreen on`.  In 2.6.26-rc4, I get lots of black
background characters."""

Another addendum to commit c9e587ab.  This was previously missed out since
I was not aware of what vc_decscnm was for.
