Older udev versions (udev < v165), don't have the official udev_device_get_is_initialized function available to query for device initialization state in udev database. Also, devices don't have USEC_INITIALIZED udev db variable set - this is bound to the udev_device_get_is_initialized fn functionality. In this case, check for "DEVLINKS" variable instead - all block devices have at least one symlink set for the node (the "/dev/block/<major:minor>". This symlink is set by default basic udev rules provided by udev directly. We'll use this as an alternative for the check that initial udev processing for a device has already finished.
