  Don't crash when passing a NULL message to __astman_get_header.

  Before this commit, __astman_get_header would blindly dereference the passed in
  'struct message *' to traverse the header list.  There are cases, however, such
  as '*CLI> sip qualify peer foo' where the message pointer is NULL, so we need
  to check for that.
