cilium: Fix variable naming for labels

A single IP can only have exactly one identity. Each identity can have a
set of labels associated with it. This code was confusingly using the
variable name 'identities' for individual labels within a single
identity. Rename it for clarity.

(Strictly speaking the labels may not actually be labels but may be the
numeric identity if the user decided not to pretty-print the labels, but
I think this variable naming is still more clear than what preceded it).
