prima: Enable split scan immediately after GO is started

Currently split scan is enabled when stats timer is invoked
(hdd_tx_rx_pkt_cnt_stat_timer_handler).It could be possible that,
during a P2P connection after GO is started, a scan is triggered
before the stat timer is invoked leading to a full scan, due to
which a client can receive a beacon miss resulting in connection
failure or disconnection.
