BUG/MINOR: ssl: free correctly the sni in the backend SSL cache

__ssl_sock_load_new_ckch_instance() does not free correctly the SNI in
the session cache, it only frees the one in the current tid.

This bug was introduced with e18d4e8 ("BUG/MEDIUM: ssl: backend TLS
resumption with sni and TLSv1.3").

This fix must be backported where the mentionned commit was backported.
(all maintained versions).
