Subject: [PATCH net-next 8/9] selftests: drv-net: psp: lift psp connection
 setup out of _data_basic_send() testcase

This is a pure refactor, so that the key exchange sequence can be used
in other test cases that start with a key exchange, but might choose
to perform different tx/rx patterns afterwards.
