qcacld-3.0: Configure proper default scan mode while roaming

Currently, host configures scan mode as ROAM_TRIGGER_SCAN_MODE_PARTIAL
instead of ROAM_TRIGGER_SCAN_MODE_NONE via
WMI_ROAM_ENABLE_DISABLE_TRIGGER_REASON_CMDID command for below roam
reasons:
WMI_ROAM_TRIGGER_REASON_BSS_LOAD
WMI_ROAM_TRIGGER_REASON_BTM
WMI_ROAM_TRIGGER_REASON_LOW_RSSI
WMI_ROAM_TRIGGER_REASON_BMISS
WMI_ROAM_TRIGGER_REASON_PER
WMI_ROAM_TRIGGER_REASON_PMK_TIMEOUT

Fix is to send proper by-default scan mode while roaming.
