wifi: iwlwifi: mvm: don't check dtim_period in new API

In newer firmware APIs the firmware is responsible for tracking
the DTIM period and other beacon timing, so we don't need to
wait with setting associated. In real MLO operation, mac80211
isn't tracking this anyway, and connections wouldn't work.
