wifi: ath12k: do WoW offloads only on primary link

In case of multi-link connection, WCN7850 firmware crashes due to WoW
offloads enabled on both primary and secondary links.

Change to do it only on primary link to fix it.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00284-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1

Fixes: 32f7b19668bd ("wifi: ath12k: support MLO as well if single_chip_mlo_support flag is set")
