qcacmn: Enable RPS dynamically for SAP mode

SAP Rx TPUT is bounded by host network stack, which is running in the
context of IPA work-queue, when IPA offload data path enabled.
However RPS shouldn't enabled for legacy Rx data path, where NAPI is
enabled. So, we dynamically enable RPS for SAP interface when the vdev
comes up and IPA was enabled only.
Send RPS enable indication to CNSS daemon to enable RPS only when SAP
interface comes up and disable RPS when SAP interface is closed.
