socket: only free socket after successful creation of new
When an interface is down, the socket port can change freely. A socket
will be allocated when the interface comes up, and if a socket can't be
allocated, the interface doesn't come up.
However, a socket port can change while the interface is up. In this
case, if a new socket with a new port cannot be allocated, it's
important to keep the interface in a consistent state. The choices are
either to bring down the interface or to preserve the old socket. This
patch implements the latter.
