[PATCH] daemon: unbreak NO_IPV6 build regression

[Junio C Hamano <gitster@pobox.com>]

When 01cec54e (daemon: deglobalize hostname information, 2015-03-07)
wrapped the global variables such as hostname inside a struct, it
forgot to convert one location that spelled "hostname" that needs to
be updated to "hi->hostname".

This was inside NO_IPV6 block, and was not caught by anybody.
