qcacld-3.0: Send full roam scan period to userspace upon querying

Browse source 
Userspace may query for current configured full roam scan period
through the vendor cmd QCA_WLAN_VENDOR_ROAMING_SUBCMD_CONTROL_GET
and the attribute QCA_ATTR_ROAM_CONTROL_FULL_SCAN_PERIOD.
Fill the full scan period in the same attribute and send as reply
