MINOR: listener: use the protocol's ->rx_resume() method when available

Instead of calling listen() for IPPROTO_TCP in resume_listener(), let's
call the protocol's ->rx_resume() method when defined, which does the same.
This removes another hard-dependency on the fd and underlying protocol
from the generic functions.
