Subject: mac80211: fix packet statistics for fast-RX

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

commit 0328edc77d4f35014b35f32b46be0a7e16aae74f upstream.

When adding per-CPU statistics, which added statistics back
to mac80211 for the fast-RX path, I evidently forgot to add
the "stats->packets++" line. The reason for that is likely
that I didn't see it since it's done in defragmentation for
the regular RX path.

Add the missing line to properly count received packets in
the fast-RX case.
