Subject: [PATCH] mac80211: util: don't warn on missing sband iftype data

The kernel currently floods the ringbuffer with warnings when adding a
mesh interface for a device not support HE 6GHz modes.

Return without warning in this case, as mesh_add_he_6ghz_cap_ie calls
ieee80211_ie_build_he_6ghz_cap regardless of the supported interface
modes.
