net/tcp: remove debug counter of connect instance

Browse Source 
Fixed by commit:

 | net: remove pvconn reference from all devif callback
 |
 | Do not use 'pvconn' argument to get the connection pointer since
 | pvconn is normally NULL for some events like NETDEV_DOWN.
 | Instead, the connection pointer can be reliably obtained from the
 | corresponding private pointer.
