Do not dereference the channel if AST_PBX_KEEPALIVE has been returned.

This is a bug I noticed while looking at the code for app_macro.  This return code
means that another thread has assumed ownership of the channel and it can no longer
be touched.  (I hate this return code with a passion, by the way.)
