[RFC]Documentation:accounting:getdelays.c Fix: warning: variable ‘i’ set but not used

["Justin P. Mattock" <justinmattock@gmail.com>]

The below patch takes care of the warning, but keep in mind am unsure if this is a correct way
to resolve this issue.
Documentation/accounting/getdelays.c: In function ‘main’:
Documentation/accounting/getdelays.c:436:7: warning: variable ‘i’ set but not used [-Wunused-but-set-variable]

Keep in mind there is another warning with this file, but need am unsure what might be the best solution:
Documentation/accounting/getdelays.c: In function ‘get_family_id’:
Documentation/accounting/getdelays.c:172:14: warning: variable ‘rc’ set but not used [-Wunused-but-set-variable]
