This patch changes to use __le types directly in the dlm message structure which is casted at the right dlm message buffer positions. The main goal what is reached here is to remove sparse warnings regarding to host to little byte order conversion or vice versa. Leaving those sparse issues ignored and always do it in out/in functionality tends to leave it unknown in which byte order the variable is being handled.
