net: dev_close() should check IFF_UP
Commit 443457242beb (factorize sync-rcu call in
unregister_netdevice_many) mistakenly removed one test from dev_close()
Following actions trigger a BUG :
modprobe bonding
modprobe dummy
ifconfig bond0 up
ifenslave bond0 dummy0
rmmod dummy
dev_close() must not close a non IFF_UP device.
