wifi: ath12k: fix link valid field initialization in the monitor Rx
[ Upstream commit 2826139f9295821fe2b049318a1cc057ec003131 ]
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.
