wifi: mac80211: fix mesh id corruption on 32 bit systems
Since the changed field size was increased to u64, mesh_bss_info_changed
pulls invalid bits from the first 3 bytes of the mesh id, clears them, and
passes them on to ieee80211_link_info_change_notify, because
ifmsh->mbss_changed was not updated to match its size.
Fix this by turning into ifmsh->mbss_changed into an unsigned long array with
64 bit size.
Fixes: 15ddba5f4311 ("wifi: mac80211: consistently use u64 for BSS changes")
