qcacld-3.0: Add feature flag for connection roaming ini

Currently driver don't have any feature flag for connection
roaming ini config and it directly tries to read the connection
roaming ini file, on some of the platforms if this ini file is
not present it returns failure message but some of the platforms
results in timeout which results in unexpected behavior.

To address above issue add a feature flag to read connection
roaming ini config.
