[PATCH] ipv4: don't call upper-layer disconnect function if not connected

Calling connect() with AF_UNSPEC will disconnect a socket, but we don't 
need to do any work if the socket isn't currently connected.

The socket could have been bind()'d to, in which case it will
not move to connected state and we still need to invoke
the disconnect methods such as udp_disconnect() to clear out
that binding.

You seem to be groveling in random areas of the ipv4 and ipv6 stack,
what are you working on?

Ok.

Was looking into a customer-reported memory leak that seemed to be in 
this code path.  It wasn't, but this tweak seemed sane at the time.
