Fix ILIST_DEBUG build
In c8ad4d8166a dlist_member_check()'s arguments were made const. Unfortunately
the implementation of dlist_member_check() used dlist_foreach(), which
currently doesn't work for const lists.
As a workaround, open-code the list iteration. The other check functions
already do so.
