mdig: fix implicit bool to int cast

The `display_rrcomments` is a tri-state (-1, 0, 1) which is (in some
cases) initialized with `state`, a boolean, through an implicit cast.
This was spot by Coccinelle. Remove the implcit cast by explicitly
assigning 0 or 1 to `display_rrcomments` based on `state` value.

(cherry picked from commit 25f303f0466ffc821b87ca9aced5935dcaa0be21)
