bonding: make speed, duplex setting consistent with link state

Browse source

bond_update_speed_duplex() retrieves speed and duplex settings. There
is a possibility of failure in retrieving these values but caller has
to assume it's always successful. This leads to having inconsistent
slave link settings. If these (speed, duplex) values cannot be
retrieved, then keeping the link UP causes problems.

The updated bond_update_speed_duplex() returns 0 on success if it
retrieves sane values for speed and duplex. On failure it returns 1
and marks the link down.
