Subject: [PATCH] netdev_alloc_pcpu_stats: use less common iterator variable

From: Johannes Berg <johannes.berg@...el.com>

With the CPU iteration variable called 'i', it's relatively easy
to have variable shadowing which sparse will warn about. Avoid
that by renaming the variable to __cpu which is less likely to
be used in the surrounding context.
