Subject: Small fixes - see full log.

Remove code to skip interfaces that do not have IP addresses configured.
  This checking is redundant now, and prevents interfaces being brought up
  without IP addresses - which is important for bridging/bonding/VLANs.
When grabbing the vlan ID from the interface name, use ## instead of #.
Move the point where bridges are taken down to before the point where
  wireless interfaces are taken down.  This is required so that a bridge
  on a wireless interface is take down before the interface itself.
When looping through the interfaces to take down, use MAXNICS-1.
