Change subject: chan_sip: Fix early call pickup channel leak.
......................................................................

chan_sip: Fix early call pickup channel leak.

When handle_invite_replaces() was called, and either ast_bridge_impart()
failed or there was no bridge (because the channel we're picking up was
still ringing), chan_sip would leak a channel.

Thanks Matt and Corey for checking the bridge path.
