wlan: Implement Private NL CMD handling for roaming
When supplicant issue enabled / disable firmware based
roaming on the basis of the Bssid modification in network
block for an (e.g. AutoJoin modify Network Block N/W),
That time middle-ware will issue this pvt cmd to Driver.
Driver need to disable / enable firmware roaming.
(in our current design we can enable firmware roaming
by offload scan to firmware so firmware can scan and
find candidate ap when rssi threshold meet the criteria,
same way driver can stop firmware roaming by stop offload
scan to firmware).
