core: ensure unique unit for VirtIO_SCSI and SPAR_VSCSI disks Ensuring a unique address unit value for disks attached with VirtIO_SCSI or SPAR_VSCSI interfaces. The selected units may collide as the search process is depended on the VmDevice addresses which are updated asynchronously by the VmsMonitoring. E.g. when hot-plugging multiple disks using a script, identical unit values might be selected for different disks. Hence: * Moved address creation logic to BLL layer (AbstractDiskVmCommand). * Updating VmDevice address in DB right after selecting an available unit value. * Taking an EngineLock on 'getDiskAddressMap' method to avoid races.
