The following patch (based on a patch from Stephen Hemminger
<shemminger@xxxxxxxxxxxxxxxxxxxx>) removes use after free conditions in
the unregister path for the bonding master. Without this patch, an
operation of the form "echo -bond0 > /sys/class/net/bonding_masters"
would trigger a NULL pointer dereference in sysfs. I was not able to
induce the failure with the non-sysfs code path, but for consistency I
updated that code as well.

I also did some testing of the bonding /proc file being open
while the bond is being deleted, and didn't see any problems there.

Hey David, this patch fixes one of the bugs listed in 2.6.22-rc5
list. Jay submitted last week but it hasn't made it upstream.

Get him to forward it to me, like he does for other bonding patches...
