wifi: mac80211: add helpers to access sband iftype data

Browse Source 
There's quite a bit of code accessing sband iftype data
(HE, HE 6 GHz, EHT) and we always need to remember to use
the ieee80211_vif_type_p2p() helper. Add new helpers to
directly get it from the sband/vif rather than having to
call ieee80211_vif_type_p2p().

Convert most code with the following spatch:

    @@
    expression vif, sband;
