drm/amdkfd: Fix updating IO links during device removal

The logic to update the IO links when a KFD device
is removed was not correct as it would miss updating
the proximity domain values for some nodes where the
node_from and node_to both were greater values than the
proximity domain value of the KFD device being removed
from topology.
