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.
