[ Upstream commit 164272113b ]
This patch sets the stop tx flag before we commit the dlm message.
This flag will report about unexpected transmissions after we
send the DLM_FIN message out, which should be the last message sent.
When we commit the dlm fin message, it could be that we already
got an ack back and the CLOSED state change already happened.
We should not set this flag when we are in CLOSED state. To avoid this
race we simply set the tx flag before the state change can be in
progress by moving it before dlm_midcomms_commit_mhandle().
