Fix another bug specifically related to asynchronous call origination. Once the

PBX is started on the channel using ast_pbx_start(), then the ownership of the
channel has been passed on to another thread.  We can no longer access it in this
code.  If the channel gets hung up very quickly, it is possible that we could
access a channel that has been free'd.
