Remove DriveStatus::CleaningUp from activeDriveStatuses in OStoreDB

The state CleaningUp is introducing a lot of problems when the system tries to look for an existing or next mount. If it's in cleaning up state is because something happened and the tape drive should be put DOWN, so search for the mount shouldn't be necessary.

Also it's recommendable to log when a tape drive with NO_MOUNT is read to get the type of mount1.
