Change subject: res_pjsip_send_to_voicemail.c: Fix off-nominal double channel unref.
......................................................................

res_pjsip_send_to_voicemail.c: Fix off-nominal double channel unref.

* Fix double unref of other_party channel in off nominal path.

* This is unlikely to be a real problem.  However, for safety,
in handle_incoming_request() keep the datastore ref with the
other_party channel ref until we are finished with the other_party
channel.
