The returned port from getservbyname() is in
network order. Convert the port to host order
before writing it to the portlist file.

/etc/services has:

nfsrdma    20049/tcp
nfsrdma    20049/udp
nfsrdma    20049/sctp

which RFC 5666 defines, but I couldn't find in the
IANA protocols registry.

 struct servent *sv = getservbyname("nfsrdma", "tcp");

Is weird.
