[PATCH 2/6] bonding: fix sparse warnings

[Stephen Hemminger <shemminger@vyatta.com>]

[-- Attachment #1: bonding-sparse.patch --]
[-- Type: text/plain, Size: 1997 bytes --]

This fixes sparse warnings due to normal locking, and shadowed variable.
There is still one warning but it is valid, and caused by some dubious locking
in the failover MAC assignment.
