if_bridge panic removing member

[David ROFFIAEN]

Hi list,

On FreeBSD 9-stable (csup from today) with amd64 arch (only, no poblem 
with the same source on i386) kernel panic when removing member form the 
bridge :
to reproduce :

# ifconfig bridge0 create addm em0
# ifconfig bridge0 deletem em0

the problem is the same with all interfaces (tested with wlan vlan em)

It seems to become for a new function in net/if_bridge.c :  
bridge_linkstate, not existing previously when it worked on amd64 (one 
month ago)

Sorry for my english

David
