Johan Hovold 58c85123d9 greybus: es1/2: fix use-after-free in completion callback 
Reset the hcpriv field before returning the message to greybus core in
the OUT-URB completion callback.

This fixes a use-after-free bug when sending responses to incoming
requests as the final reference is then dropped when the message is
returned.
