udev-node: assume no new claim to a symlink if /run/udev/links is not updated

Browse Source 
During creating a symlink to a device node, if another device node which
requests the same symlink is added/removed, `stat_inode_unmodified()`
should always detects that. We do not need to continue the loop
unconditionally.
