[PATCH V6 1/5] rpmsg: glink: Use complete_all for open states

[Arun Kumar Neelakantam]

From: Chris Lew <c...@codeaurora.org>

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