ice: initialize ring_stats->syncp

ice: initialize ring_stats->syncp

The u64_stats_sync structure is empty on 64-bit systems. However, on 32-bit
systems it contains a seqcount_t which needs to be initialized. While the
memory is zero-initialized, a lack of u64_stats_init means that lockdep
won't get initialized properly. Fix this by adding u64_stats_init() calls
to the rings just after allocation.
