Wlan: Enable scan split feature in SME for multiple session scenario

Enable the scan logic to breakdown the scan request into multiple scan
commands and provide a gap between scans on individual channels. During
the gaps the device returns to the home channel and provides an
opportunity for traffic on the home channel.
