Katyanna Moura 71a8e99d1f Fix panic when trying to add key to nil map
Bug was introduced trying to solved the following issue:
> When scenarios where two HPAs reference the same object but have
different metric calculation (e.g. ingresses with different weights),
kube-metrics-adapter calculates the two metrics but always overrides
one of the metrics when saving it to the store.

This commit fixes a issue where without the added `return` the system
was continuing in an invalid states where `labels2metric` wasn't
properly initialized, causing the system to panic.
