Subject: ixgbe: Initialize 64-bit stats seqcounts
Patch-mainline: v4.13-rc5
Git-commit: 7c3a4626eb65e78ebe208f48ffa21a5002f7f38e
References: bsc#1056657 FATE#322189 bsc#1056653 FATE#322190

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.
