qcacld-3.0: Fix data stall after sta roaming disabled and reconnection

Browse source 
When reassociate, roaming is disabled by wpa_supplicant, but RSO stop
reason REASON_SUPPLICANT_DISABLED_ROAMING is ignored and roam scan mode
isn't cleared to 0 before vdev WMI_ROAM_FW_OFFLOAD_ENABLE_FLAG flag is
cleared. Then host can't receive peer unmap/map event when wlan disconnect
and reconnect, host dp peer id isn't updated, Rx frames are dropped for
peer id mismatch.

Fix: When roaming is disabled, make sure roam scan mode is cleared to 0
before vdev WMI_ROAM_FW_OFFLOAD_ENABLE_FLAG flag is cleared.
