qcacld-3.0: Always set WMI_ROAM_SCAN_MODE_NONE with RSO_STOP cmd for LFR2.0

For LFR2.0 roaming policy, firmware will indicate roam event with
WMI_ROAM_REASON_SUITABLE_AP reason even ROAM_SCAN_OFFLOAD_STOP cmd
set with WMI_ROAM_SCAN_MODE_ROAMOFFLOAD, it doesn't obey LFR2.0
roaming policy design. Root cause is firmware only disable roam
scan with ROAM_SCAN_OFFLOAD_STOP cmd which must set scan mode with
WMI_ROAM_SCAN_MODE_NONE.

Fix is to always set scan mode with WMI_ROAM_SCAN_MODE_NONE for
LFR2.0 when host send ROAM_SCAN_OFFLOAD_STOP cmd.
