John Fastabend d85f017758 net: tls, fix sk_write_space NULL write when tx disabled ... The ctx->sk_write_space pointer is only set when TLS tx mode is enabled. When running without TX mode its a null pointer but we still set the sk sk_write_space pointer on close(). Fix the close path to only overwrite sk->sk_write_space when the current pointer is to the tls_write_space function indicating the tls module should clean it up properly as well.
