[PATCH net-next v2 9/9] net: bridge: pack net_bridge better

[Nikolay Aleksandrov <nikolay@cumulusnetworks.com>]

Further reduce the size of net_bridge with 8 bytes and reduce the number of
holes in it:
 Before: holes: 5, sum holes: 15
 After: holes: 3, sum holes: 7

Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com>

v2: Remove the comment about offload_fwd_mark in net_bridge and
    leave it, the change will be for net_bridge_port instead.
    Thanks to Ido for spotting it.
