[TCP]: NewReno must count every skb while marking losses
NewReno should add cnt per skb (as with FACK) instead of depending on SACKED_ACKED bits which won't be set with it at all. Effectively, NewReno should always exists after the first iteration anyway (or immediately if there's already head in lost_out. This was fixed earlier in net-2.6.25 but got reverted among other stuff and I didn't notice that this is still necessary (actually wasn't even considering this case while trying to figure out the reports because I lived with different kind of code than it in reality was). This should solve the WARN_ONs in TCP code that as a result of this triggered multiple times in every place we check for this invariant.
