fix dsm and copy range setup

fix dsm and copy range setup

The argconfig array helpers parse into int and unsigned long long
arrays. In the copy function we are casting an int* to __u16* and we end
up with wrong values. Instead, just use the types in the setup functions
directly and convert the individual values as part of calling the
cpu_to_le* helpers.

While copy is the one that is immediately broken on most systems, do
this for DSM as well since it breaks on systems where int is not 32
bits.
