    tcp: handle pcb->snd_queuelen and chained pbufs during segment split (bug 
#52692)
    
    This fixes a bug in tcp_split_unsent_seg() where a chained pbuf was
    not correctly updating pcb->snd_queuelen during trimming and snd_queuelen
    would desynchronize if pbuf_realloc() freed some of the chain
    
    Also, use pbuf_clen() for adding the new remaining segment rather than ++.
    The new remaining segment should always be one pbuf due to the semantics
    of PBUF_RAM, but this follows the best practice of using pbuf_clen()
