[PATCH] bonding: fix slave speed reporting in bond_miimon_commit

[nikolay@redhat.com]

From: Nikolay Aleksandrov <nikolay@redhat.com>

When we have BOND_LINK_UP the speed is reported unconditionally with %u
format although it can be SPEED_UNKNOWN (-1). After this patch it returns
0 in that case in an attempt to keep the existing scripts happy.
One line is intenionally left 81 chars because it gets ugly if broken.

If the scripts are not a concern I can re-post with a string "unknown".
