qcacld-3.0: Fix SAP get peer state error in AP+AP mode

WLAN driver working on AP0+AP1 mode. After a ref STA move
connection from AP0(vdev0) to AP1(vdev1). vdev0 have release
peer STA. But it can get a peer state from ol_txrx_get_peer_state.
Actually, the state is from vdev1, not vdev0. If vdev0 have data
send to FW, it will cause FW crash.
