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

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.

(cherry picked from commit 8f27311eb2aec2411d1fb7d62e6c9d75d21ae8df)
