qcacmn: Tput is low when DS is enabled in STA

Issue:
When DS mode is configured for a VAP
in both AP and STA (RDP 433), the tput reduces.
For instance, for an ingress of 7G
in standalone case, the egress rate is
1) 6887 Mbps when DS is enabled only in AP
2) 1900 Mbps when DS is enabled in both AP and STA
RCA:
With the help of debugs & proc/interrupts, identified
that we are not setting up the peer when the
device in STA mode due to AP mode check in
dp_soc_txrx_peer_setup.
Hence, the traffic is not flowing via DS
and so, tput reduces.

Fix:
Added changes to invoke txrx_peer_setup in
STA mode and DS mode will configured in that mode.
With the fix, traffic flows via DS, which
in turn improves the increased
