udev: update devlink with the newer device node even when priority is equivalent

udev: update devlink with the newer device node even when priority is equivalent

Several udev rules depends on the previous behavior, i.e. that udev
replaces the devlink with the newer device node when the priority is
equivalent. Let's relax the optimization done by
331aa7aa15ee5dd12b369b276f575d521435eb52.

Follow-up for 331aa7aa15ee5dd12b369b276f575d521435eb52.

Note, the offending commit drops O(N) of file reads per uevent, and this
commit does not change the computational order. So, hopefully the
performance impact of this change is small enough.

Fixes #28141.
