  Fixes locking inversion issue in ast_async_goto()
  
  During this function we can not hold the "chan" lock while
  doing the masquerade, the explicit goto on the tmp chan, or
  the channel alloc.  Instead we need to get the channel lock,
  store off information about the channel that we need, and
  then let the channel lock go for the remainder of the function.
