Security parameters for each non-transmitting profile can be
different when MBSSID is enabled and this information is included
in the MBSSID element in the Beacon frame. Current implementation
to set rsnie_present and wpaie_present does not parse this element
hence it applies only to the transmitting interface.

Move the code to a separate function to make additions for
non-transmitting interfaces cleaner.

Tested-on : IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

v3: Renamed ath11k_mac_setup_bcn_tmpl_vif_params(0 as
    ath11k_mac_set_vif_params() as the parameters are not actually
    set in the Beacon frame. MLO link ID change is not required
    anymore.

v2: Changed calls to mac80211 APIs to include MLO link ID.
