bonding: force carrier update when releasing slave

Browse source 
commit a6ab75cec1e461f8a35559054c146c21428430b8 upstream.

In __bond_release_one(), bond_set_carrier() is only called when bond
device has no slave. Therefore, if we remove the up slave from a master
with two slaves and keep the down slave, the master will remain up.

Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond))
statement.

Reproducer:
$ insmod bonding.ko mode=0 miimon=100 max_bonds=2
$ ifconfig bond0 up
$ ifenslave bond0 eth0 eth1
$ ifconfig eth0 down
$ ifenslave -d bond0 eth1
$ cat /proc/net/bonding/bond0
