[PATCH V7 1/4] rpmsg: glink: Use complete_all for open states

[Deepak Kumar Singh]

From: Chris Lew <clew@xxxxxxxxxxxxxx>

The open_req and open_ack completion variables are the state variables
to represet a remote channel as open. Use complete_all so there are no
races with waiters and using completion_done.
