[PATCH] fbcon: don't repaint the cursor when it is disabled.

Currently even when the cursor is disabled (`setterm -cursor off`), it is
still repainted as a black rectangle the size of a single char.  This can
be seen, for example, by chvt'ing to a free tty, disabling the cursor and
doing `dd if=3D/dev/urandom of=3D/dev/fb0`.

The patch changes this behaviour by avoiding painting anything when the
cursor is disabled.
