[PATCH 1/1] hostapd: Use attribute NL80211_ATTR_BSSID to trigger scan for specifc BSSID

With changes to optimize scan for specific BSSID, there arises a
scenario where in nl80211_trigger_scan is called with a scan
randomization enabled. A combination of NL80211_ATTR_MAC and
scan randomization results in invalid error for the scan request.
In order to fix the issue we use attribute NL80211_ATTR_BSSID
instead of NL80211_ATTR_MAC.
