MINOR: sock: rename sock to sock_fd in sock_create_server_socket

Renaming sock to sock_fd makes it more clear, that sock_create_server_socket
returns the fd of newly created server socket and then we check this fd.
As we heavily use "fd" variable name in all protocol implementations, let's
prefix this one with the name of its object file: sock.o.
