tls: fix OpenSSL compression leak that breaks tests under ASAN

[pimterry]

This is not impactful for normal users at all - it's a fixed leak of the openssl record compression descriptors, about 24 bytes leaked total, once per process.

It is very annoying though if you want to run with ASAN & leak detection to check for other issues. It's an unambiguous memory leak we hit effectively every run where crypto is used.

The change here ensures we individually free the descriptors, in addition to emptying the stack that references them. There's an existing test that confirms this doesn't accidentally re-enable record compression somehow.
