[PATCH] fbcon_do_set_font() sanitized

	fbcon internal cleanup.  Instead of passing console_font_op into
fbcon_do_set_font() we pass width/height directly.  Amusing (but harmless)
bug fixed there:
	if (!w > 32) {
		bogus code that fortunately never got triggered
	}
Fixed by removal of the junk in question (and yes, it's verifiable junk -
it would not do anything even if we replaced the check with intended
!(w > 32)).
