qcacmn: Add return path for fc_peer_stats for peer mac address

Add return path for fc_peer_stats for peer mac address if the peer
is connected to another pdev.

The DP peers are maintained at the SOC as such there is no check
to make sure that the peer is for a particular pdev.

This issue is especially seen when an end user invokes
fc_peer_stats in wifi0 for a peer that is connected to wifi1. In
such a case, we should be returning an error since the peer is not
connected to the pdev that the user application is directed to.
