Subject: bonding: don't hold lock when calling rtnl_unlock
From: Jay Vosburgh <[EMAIL PROTECTED]>
Change bond_mii_monitor to not hold any locks when calling rtnl_unlock,
as rtnl_unlock can sleep (when acquring another mutex in netdev_run_todo).
Bug reported by Makito SHIOKAWA <[EMAIL PROTECTED]>, who
included a different patch.
