librb: commio: Must set addrlen before every call to accept()

If an IPv4 connection is dropped by the pre-callback, and there is a
pending IPv6 connection on the same listening socket then the retried
accept() will be unable to populate `st` because `addrlen` will be too
small. Also initialise `st` each time to avoid a clang static analysis
warning.
