idpf: Fix data race in idpf_net_dim

Browse source

In idpf_net_dim(), some statistics protected by u64_stats_sync, are read
and accumulated in ignorance of possible u64_stats_fetch_retry() events.
The correct way to copy statistics is already illustrated by
idpf_add_queue_stats(). Fix this by reading them into temporary variables
first.
