[PATCH 3.16 087/294] ixgbe: Initialize 64-bit stats seqcounts

[Ben Hutchings]

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@xxxxxxxxx>

commit 7c3a4626eb65e78ebe208f48ffa21a5002f7f38e upstream.

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.

Fixes: 4197aa7bb818 ("ixgbevf: provide 64 bit statistics")
