[BRIDGE]: recompute features when adding a new device

Browse Source 
We must recompute bridge features everytime the list of underlying 
devices changes, or we might end up with features that are not
supported by all devices (eg. NETIF_F_TSO)
This patch adds the missing recompute when adding a device to the bridge.
