qcacld-3.0: Fix the issue with duplicate HE caps advertisement

Browse source 
HE caps and HE op IE are derived in driver and also sent from
hostapd as part of additional IE. additional IEs are appended at
end of the beacon frame hence the duplicate IEs are observed.
Strip out the HE caps and HE op IE from additional IE after the
IEs are derived in driver.
