BUG/MEDIUM: ssl: Properly initialize msg_controllen.

When kTLS is compiled in, make sure msg_controllen is initialized to 0.
If we're not actually kTLS, then it won't be set, but we'll check that
it is non-zero later to check if we ancillary data.
This does not need to be backported.
This should fix CID 1620865, as reported in github issue #3106.
