Update snd_queuelen comment documentation

Browse Source 
This commit updates the snd_queuelen comment documentation to reflect
that snd_queuelen tracks the number of pbufs currently in the send
buffer (unsent + unacked queues) rather than the number of pbufs
available in the buffer (which was what previous comment implied)
