We can not set IV when we are under reset. Previously we read previous IV value from registers and zeroed IV registers when key was deleted, but this could possibly not work if DEL_KEY command was not performed. Now when we have ->reconfig_complete ops and we fully mark mac80211 reset state via DEVICE_STATE_RESET flag, we can just skip setting IV when keys are set during reset.
