qcacld-3.0: Rectify mac address validation check
In function hdd_dis_connect_handler, before calling ucfg_ipa_wlan_evt,
the driver validates the mac address being passed. Currently this
validation is not done properly and valid mac address are marked as
invalid.
Replace the incorrect validation API with the correct one.
