qcacld-3.0: Set the key installed flag to sta_ds after roam

After roaming, new pe session is created and based on the authentication
status received in the roam synch indication, the is_key_installed flag
is set. But this flag is not set to sta ds after roaming.
This causes deauth frame to roamed AP sent out unencrypted after
roam.

Set the key installed flag to sta ds if the auth status in
roam synch indication is authenticated.
If the status is connected, this flag will be set in the
set key response path.
