10155: Minor: replace old name `CrateDefMap` in comments r=jonas-schievink a=toyboot4e

This PR replaces the old name `CrateDefMap` in comments with the new name `DefMap`. The renaming was done in [57a82fb](57a82fb0) (Jan 2021).

I didn't touch the working code ([CrateDefMapQueryQuery][QQ]). Thank you.
