qcacld-3.0: Enable time sync only on connection/roam

Currently WMI_DBGLOG_TIME_STAMP_SYNC_CMDID command sent
every 1 sec causes RTPM collapse and inturn has power
impact. So to avoid this enable time of the day synchronization
only after connection/roaming.

Send WMI_DBGLOG_TIME_STAMP_SYNC_CMDID as part of RSO
start command.
