qcacld-3.0: Don't generate assoc rsp for standby vdev during roam

While processing roam sync indication for link vdev, the assoc
response frame is generated and parsed to fill new pe_session.
But its parsing for the standby vdev also. This causes parsing
failure and RSO stop is sent to firmware leading to HO failure
disconnect.

so don't generate assoc rsp for standby vdev during roam
