qcacld-3.0: Set cds_ol_rx_thread schedule policy to SCHED_RR

On QCS405 platform, it's observed that cds_ol_rx_pkt_freeq is empty
while receiving UDP packets, driver try to allocate cds_ol_rx_pkt in
ol_rx_data_process but failed. This leads to lots of frames got dropped.
Raise cds_ol_rx_thread scheduler policy to SCHED_RR to compete with
CE tasklet scheduler speed. With this change, found cds_ol_rx_pkt_freeq
is not going to be empty while receiving UDP packets.
