Subject: [PATCH] netdev: octeon_mgmt: Fix ISO C90 forbids mixed declarations and code warning.

From: David Daney <david.daney@...ium.com>

We were getting:

  drivers/net/ethernet/octeon/octeon_mgmt.c:295:4: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]

The idea of the fix from Joe Perches.

This patch should supersede previous patches from Heinrich Schuchardt,
and may be preferable as it touches fewer lines of code.
