[PATCH net 5/7] gtp: Initialize 64-bit per-cpu stats correctly

[Florian Fainelli]

On 32-bit hosts and with CONFIG_DEBUG_LOCK_ALLOC we should be seeing a
lockdep splat indicating this seqcount is not correctly initialized, fix
that by using netdev_alloc_pcpu_stats() instead of an open coded
allocation.

Protocol (GTP-U)")
