As the names of (struct test_key) members didn't reflect whether the key
was used for TX or RX, the verification for the counters was done
incorrectly for asymmetrical selftests.
Rename these with _tx appendix and fix checks in verify_counters().
While at it, as the checks are now correct, introduce skip_counters_checks,
which is intended for tests where it's expected that a key that was set
with setsockopt(sk, IPPROTO_TCP, TCP_AO_INFO, ...) might had no chance
of getting used on the wire.
Fixes the following failures, exposed by the previous commit:

The end_server() function only operates in the server thread
and always takes an accept socket instead of a listen socket as
its input argument. To align with this, invert the boolean values
used when calling verify_counters() within the end_server() function.
As a result of this typo, the test didn't correctly check for
the non-symmetrical scenario, where i.e. peer-A uses a key <100:200>
to send data, but peer-B uses another key <105:205> to send its data.
So, in simple words, different keys for TX and RX.

Check multiple keys on a socket:
- rotation on closed socket
- current/rnext operations shouldn't be possible on listen sockets
- current/rnext key set should be the one, that's used on connect()
- key rotations with pseudo-random generated keys
- copying matching keys on connect() and on accept()
At this moment there are 3 tests that are "expected" to fail: a kernel
fix is needed to improve the situation, they are marked XFAIL.
