Log Message:
Pull up following revision(s) (requested by msaitoh in ticket #1046):

        sys/net/if_bridge.c: revision 1.157
        sys/net/if_bridge.c: revision 1.158
        sys/net/if_bridge.c: revision 1.159

  Fix a bug that bridge_enqueue() incorrectly cleared outgoing packet's offload
flags. bridge_enqueue() is called from bridge_output() when a packet is
spontaneous. Clear csum_flags before calling brige_enqueue() in
bridge_forward() or bridge_broadcast() instead of in the beginning of
bridge_enqueue().

Note that this change doesn't fix a problem on the following configuration:

        A bridge has two or more interfaces.
        An address is assigned to an bridge member interface and
        some offload flags are set.
        Another interface has no address and has no any offload flag.

XXX pullup-[78]

- Fix bridge_enqueue() which was broken by last commit. Use correct mbuf
   pointer.
- Modify comment.

Micro optimization. m_copym(M_COPYALL) -> m_copypacket().
