[dpdk-dev] [PATCH] eal/windows: ensure all the CPUs in the set are checked

From: Narcisa Vasile <navasile at microsoft.com>

Fix count_cpu() to ensure it iterates through all the CPUs in a set.
count_cpu() iterates through the CPUs in the set 's' and counts the
selected ones.

Previously, it was incorrectly using the number of CPUSETS to iterate
through the CPUs.
