Add tags with length 0 for MLO header and partner links which
are required by the firmware for a successful association.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1

v4: No change from v3.
v3: Moved MLO header tag addition before EHT rates to match firmware order.
v2: Corrected 'witout' to 'without' in the description.
