Bridge down should only affect that bridge

This patch was provided by QCA support, case SF05053344.  The patch was
corrupt, but the intent was pretty clear.

It fixes the issue where setting one bridge down will affect traffic on
all bridges with vlan interfaces of the same eth iface.

Update: Limit the fix to IPQ807x only, since IPQ60xx seems fine without
the fix.
