selftests: tls: fix chacha+bidir tests
ChaCha support did not adjust the bidirectional test.
We need to set up KTLS in reverse direction correctly,
otherwise these two cases will fail:
tls.12_chacha.bidir
tls.13_chacha.bidir
Fixes: 4f336e88a870 ("selftests/tls: add CHACHA20-POLY1305 to tls selftests")
