-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Move the conflicting declaration to the end of the structure. Notice that `struct ieee80211_chanctx_conf` is a flexible structure --a structure that contains a flexible-array member. Also, remove an unused structure.
