One way audio before answering call waiting call on analog port.

* Analog call waiting Caller ID spills could get stuck resulting in one
way audio until the waiting call is answered.  This only happens on the
second (and later) call waiting call if the active call is not the first
call.

* The CLI/AMI "dahdi show channel" command could report the wrong channel
information.

Must keep the struct analog_pvt.owner and struct dahdi_pvt.owner pointer
in sync.
