Currently, the link_valid field is not initialized in the monitor Rx path.
This can result in random values for the link_valid and link_id leads to
undefined behaviour in mac80211. Therefore, initialize the link_valid
field in the monitor Rx path.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
