rpmsg: smd: Reduce restrictions when finding channel
SMD channels are created by the remotes in "opening" state, but sometimes as we close and try to reopen them they linger in closing state. Following the search for a matching channel the create_ept() will verify that the channel is in a suitable state, so we can lax the restrictions of the search function to work around above difference in behaviour.
