selftests: drv-net: psp: swap closed for connected sockets in assoc tests

Future work will only allow rx-assoc and tx-assoc to be performed when
the sock is in TCP_ESTABLISHED state.

Several assoc_ tests, as well as dev_rotate_spi, test using the rx-assoc
and tx-assoc uapi calls against sockets in TCP_CLOSE state.
These tests don't involve sending or receiving data, nor involve looking
up psp device by dst entry, so using a disposable disconnected socket
was just a convenience. These can be replaced by a disposable loopback
socket.

The loopback sockets are IPv4, where the sockets they replace were
AF_INET6. This doesn't reduce coverage, since the assoc handlers accept
any TCP socket and don't look at the address family.

Some users of rx-assoc and tx-assoc on closed sockets are left if they
validate errors that are returned before the kernel will check the
socket for TCP_ESTABLISHED.
