Like someone (whose message I cannot find just now) mentioned in another
thread, just now it is right time to mention here too...

https://www.gnu.org/software/emacs/manual/html_node/elisp/Hooks.html

... that when hook name ends with `-hook` it is supposed to be "normal hook"
-- a function which does not take arguments nor return values.

So, I'd like to suggest that this variable is renamed to 
notmuch-address-completion-functions
