channel: No hung-up on failing security requirements.

In your Diaplan, if you specify
 same => n,Set(CHANNEL(secure_bridge_media)=1)
 same => n,Set(CHANNEL(secure_bridge_signaling)=1)
only the SIP channel driver chan_sip supports this. All other channels drivers
like res_pjsip fail. In case of failure, the original sRTP source code released
the whole channel, even if not hung-up, yet. This change does not release the
channel but instead hangs-up the channel.
