wcn36xx: fix the mesh STA for rejoin

The firmware has triggered the QoS NULL frame to monitor the links
amongst peer mesh STAs. Once one of the peer mesh STAs is leaving or
out of the range and no ACK received from the peer mesh STA, the
firmware will automatically delete the peer mesh STA.

After deleting the mesh STA and adding the mesh STA back with the HAL
command returning no error, the STA still won't work. Unicast data
frames is not able to transmit out from the mesh STA.

Now, re-insert the inactivite mesh STA with WCN36XX_HAL_CONFIG_STA_REQ
command with action field set to update seems to solve the problem.
