Fix downgrading of TOE TLS sockets to plain TOE.

If a TOE TLS socket ends up using an unsupported TLS version or
ciphersuite, it must be downgraded to a "plain" TOE socket with TLS
encryption/decryption performed on the host.  The previous
implementation of this fallback was incomplete and resulted in hung
connections.
