[PATCH 01/11] irqchip/gic-v3-its: Free collection mapping on device teardown

Somehow, we forgot to free the collection mapping when tearing down
a device, hence slowly leaking mapping arrays as devices get removed
from the system. That is, almost never.

Just to be safe, properly free the array on device teardown.
