[PATCH] BRIDGE: Fix faulty check in br_stp_recalculate_bridge_id()

[mikukkon@iki.fi]

I did a compile with extra gcc warnings, and found a bug in
net/bridge/br_stp_if.c function br_stp_recalculate_bridge_id():
compare_ether_addr() returns 0 if match, positive if not, so
checking it for negative is wrong.
