[PATCH v3 2/7] tools/kvm_stat: fix logging mode

[Stefan Raspl <raspl@xxxxxxxxxxxxxxxxxx>]

From: Stefan Raspl <stefan.raspl@xxxxxxxxxx>

Logging mode was broken: Stats were retrieved only once, and then printed
over and over again without refreshing.
This patch essentially restores how things were for logging mode before,
minus renaming 'k' to 'key' for better readability.

Fixes: 72664f2937d3 ("tools/kvm_stat: use a more pythonic way to iterate over dictionaries")
