Fix AP+AP IPA offload path failure when NAPI over IPA enabled on mdm
platforms by adding QCA_CONFIG_RPS check.
QCA_CONFIG_RPS is same as CONFIG_RPS, default Y, but depend on CONFIG_SMP
as msm-5.4/net/Kconfig.
For AP+AP mode,
For LA, CONFIG_SMP on, then QCA_CONFIG_RPS on, use IPA exception path.
For mdm, CONFIG_SMP off, then QCA_CONFIG_RPS off, use IPA offload path.
For IPA napi enable status check, just use qdf_ipa_get_lan_rx_napi,
don't need MACRO IPA_LAN_RX_NAPI_SUPPORT.
