be2net: fix data race in be_get_new_eqd

Browse source

[ Upstream commit 302e5b481c ]

In be_get_new_eqd(), statistics of pkts, protected by u64_stats_sync, are
read and accumulated in ignorance of possible u64_stats_fetch_retry()
events. Before the commit in question, these statistics were retrieved
one by one directly from queues. Fix this by reading them into temporary
variables first.
