[patch 20/26] [BRIDGE]: recompute features when adding a new device

From: Olaf Rempel <razzor@kopf-tisch.de>

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.
