qcacld-3.0: Show peer in getTdlsPeers only if STA is associated

qcacld-2.0 to qcacld-3.0 propagation

If the STA is previously associated with AP and has TDLS peers,
then getTdlsPeers will show the peers even after STA is
disassociated.

Thus, the fix is to show the peers only if the STA is in
connected state.
