fs: dlm: start midcomms before scand

[ Upstream commit 5282c6801f3b92cfdf91955f75f75b337c1fd0c8 ]

The scand kthread can send dlm messages out, especially dlm remove
messages to free memory for unused rsb on other nodes. To send out dlm
messages, midcomms must be initialized. This patch moves the midcomms
start before scand is started.
