qcacld-3.0: Config latency level to fw after vdev creates

From android Q, it uses a random MAC to connect to different
SSIDs which causes the interface down/up, the vdev will be
deleted and the latency level info is lost in firmware.

To fix this, save the latency level and reconfig it to fw
after vdev creates.
