[BRIDGE]: Packets leaking out of disabled/blocked ports.

This patch fixes some packet leakage in bridge.  The bridging code was
allowing forward table entries to be generated even if a device was
being blocked. The fix is to not add forwarding database entries
unless the port is active.

The bug arose as part of the conversion to processing STP frames
through normal receive path (in 2.6.17).
