qcacld-3.0: Address corner scenarios for dual sta roaming

Address below corner scenarios for dual sta roaming:

1. Initialize primary interface vdev id
with WLAN_UMAC_VDEV_ID_MAX.

2. Enable roaming while processing set primary interface
vendor command irrespective of dual sta roam policy.

3. Disable mcc_adaptive_scheduler before sending
WMI_RESMGR_ADAPTIVE_OCS_ENABLE_DISABLE_CMDID to FW and
enable it if host receives dual sta policy as unbiased.
