  remove empty audiohook write list on channel
  
  If a channel has an audiohook write list created on it, that
  list stays on the channel until the channel is destroyed.  There
  is no reason to keep that list on the channel if it becomes empty.
  If it is empty that just means we are doing needless translating
  for every ast_read and ast_write.  This patch removes the audiohook
  list from the channel once it is detected to be empty on either a
  read or write.  If a audiohook is added back to the channel after
  this list is destroyed, the list just gets recreated as if it never
  existed to begin with.
