When you sue someone for breaking the GPL, it is to make them stop distributing code which breaks the GPL. That's what you sue for, there's no monetary issues involved as the GPL'ed code is free as in beer. IANAL, but check out all those earlier cases - it's always about getting the offending distributor to stop what they're doing and do something else instead (that is, something legal). Which it appears Nokia has already done, so there's nothing to sue for anymore.
