bonding: require speed/duplex only for 802.3ad, alb and tlb
The patch c4adfc82 ("bonding: make speed, duplex setting consistent with link state") puts the link state to down if bond_update_speed_duplex() cannot retrieve speed and duplex settings. Assumably the patch was written with 802.3ad mode in mind which relies on link speed/duplex settings. For other modes like active-backup these settings are not required. Thus, only for these other modes, this patch reintroduces support for slaves that do not support reporting speed or duplex such as wireless devices. This fixes the regression reported in bug 196547 (https://bugzilla.kernel.org/show_bug.cgi?id=196547).
