r8169: use correct barrier between cacheable and non-cacheable memory
r8169 needs certain writes to be visible to other CPUs or the NIC before
touching the hardware, but was using smp_wmb() which is only required to
order cacheable memory access. Switch to wmb() which is required to
order both cacheable and non-cacheable memory.
Noticed by Catalin Marinas and Paul Mackerras.
