API change - support more const arg

Browse Source 
As dm_report_field_string() doesn't modify content of data pointer,
it can be marked as const.

It's slight API change - but doesn't require any change on the user side
and supports wider range of arguments without const casting.
(i.e. we may use as paramater const lv struct this way:  &lv->name)
