qcacld-3.0: Add support to invoke LFR3 reassoc when RSO mode is STOP

With AUTO ROAM issue, Supplicant disables roaming to other BSS
and expects driver/firmware to re-associate to a specific BSS.
Currently, host driver sets RSO to STOP[disable LFR3] completely
when supplicant invokes disable roaming and when subsequent connect
comes from supplicant, host is doing disconnect and connect.

This fix adds provision to invoke LFR3 reassociation even when
RSO Stop is issued previously to firmware. It is achieved by setting
WMI_ROAM_SCAN_MODE_ROAMOFFLOAD along with WMI_ROAM_SCAN_MODE_NONE
in mode of RSO Stop command.
