Static structure dst_config, of type dst_config, is not used except to
be assigned as the value of field state of a variable having type
dst_state *. In the definition of dst_state, field config is declared as
const. Hence dst_config, when assigned to config, cannot be modified.
Therefore, make dst_config const as well.
Issue found with Coccinelle.
