Log Message:
clean up ucom parents some more:
- it's always "bool sc_dying" now, with true/false
- heavy use of static functions
- remove all ucom parent ca_activate callbacks.  they're never called.
- callbacks should generally do little to nothing if sc_dying is set
- open resources should be released in detach after setting sc_dying
- don't complain about usbd_abort_pipe() or usbd_close_pipe() failure
- when releasing resources, zero the softc member as well
- remove ucom_methods members no longer destined to be filled in
- generally, DPRINTF() before sc_dying short circuit
- use EIO when dying, not ENXIO or 0
- add some ucom_open() callbacks that simply return EIO if dying
