iwlwifi: remove STATUS_CONF_PENDING in scanning

This patch removes STATUS_CONF_PENDING usage that called from
iwl4965_mac_config internally after scan completed.

It's called anyway from the mac80211 ieee80211_scan_completed():

	if (local->hw_scanning) {
		local->hw_scanning = false;
		if (ieee80211_hw_config(local))
		...
	}
