r8169: initialize rtl8169_stats seqlock

Boris reports he's seeing:
> [    9.195943] INFO: trying to register non-static key.
> [    9.196031] the code is fine but needs lockdep annotation.

with the r8169 driver.

These are occuring because the seqcount embedded in u64_stats_sync on
32-bit SMP is uninitialized which is making lockdep unhappy.
