Revert "bridge: Forward reserved group addresses if !STP"

BugLink: http://bugs.launchpad.net/bugs/793702

[ Upstream commit f01cb5fbea1c1613621f9f32f385e12c1a29dde0 ]

This reverts commit 1e253c3b8a1aeed51eef6fc366812f219b97de65.

It breaks 802.3ad bonding inside of a bridge.

The commit was meant to support transport bridging, and specifically
virtual machines bridged to an ethernet interface connected to a
switch port wiht 802.1x enabled.

But this isn't the way to do it, it breaks too many other things.
