    Remove out of date comment from the end of set_devices_thread()
    
    The comment became completely unnecessary with the transfer of
    mount_info and fstab_info into separate Mount_Info module by commit:
        63ec73dfdac70fde8fabb543d0a7dc5808e168d5
        Split mount_info and fstab_info maps into separate Mount_Info module
    
    It was never necessary to clear one of the mappings at the end of the
    device refresh because it was reloaded at the start of the next device
    refresh anyway and it is only a small amount of memory.
