Indeed, there's no explicit way of checking supported AKMs.  The NL80211 API 
isn't much help either:

/**
  * DOC: OWE DH IE handling offload
  *
  * By setting @NL80211_EXT_FEATURE_OWE_OFFLOAD flag, drivers can indicate
  * kernel/application space to avoid DH IE handling. When this flag is
  * advertised, the driver/device will take care of DH IE inclusion and
  * processing of peer DH IE to generate PMK.
  */

Perhaps for FullMAC, iwd should start checking for EXT_FEATURE_OWE_OFFLOAD 
presence, and if not present, do not use OWE.  Too bad no upstream driver 
actually sets this bit.  Unless... maybe OWE works with other FullMAC devices 
and we'd break things for those...?  Kernel folks really need to chime in here.
