qcacmn: Properly set RPS for WLAN IPA

It is observed on sdxpinn target (first multi-core MDM platform)
that WLAN failed to enable IPA pipes with SAP-SAP mode when first
ref-client connects to the SAP. Indeed with QCA_CONFIG_RPS=y and
qdf_ipa_get_lan_rx_napi()=true, wlan_ipa_uc_handle_first_con()
directly returns false if more than 1 SAP is started.

This obviously breaks IPA data path for MDM platform, where even
4 SAP can be supported with IPA offload. And WLAN data path
forwarding replies fully on IPA hardware. This also means there's
no need to configure RPS for MDM, which is a host kernel networking
feature.
