wireless: fix "iwlwifi: unify init driver flow"

drivers/net/wireless/iwlwifi/iwl-core.c: In function 'iwlcore_init_geos':
drivers/net/wireless/iwlwifi/iwl-core.c:323: error: implicit declaration of function 'iwlcore_init_ht_hw_capab'

This (or something like it) should be folded into the base patch to avoid
breaking bisection, please.
