net: openvswitch: fix data race in ovs_vport_get_upcall_stats
In ovs_vport_get_upcall_stats(), some statistics protected by
u64_stats_sync, are read and accumulated in ignorance of possible
u64_stats_fetch_retry() events. These statistics are already accumulated
by u64_stats_inc(). Fix this by reading them into temporary variables
first.
Fixes: 1933ea365aa7 ("net: openvswitch: Add support to count upcall packets")
