slim_msm: Keep track of satellite reconfiguring a channel

With mutiple clients able to use the same channel, it is not correct
assumption that a channel was active due to satellite client's
reconfiguration only. So during sub-system restart of a satellite,
rely on satellite-reconfiguration vote for a channel instead of
channel status to remove channels that were setup by the satellite
before sub-system restart.
