bonding: fix potential deadlock in bond_uninit()
bond_uninit() is invoked with rtnl_lock held, when it does destroy_workqueue() which will potentially flush all works in this workqueue, if we hold rtnl_lock again in the work function, it will deadlock. So move destroy_workqueue() to destructor where rtnl_lock is not held any more, suggested by Eric. Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Jay Vosburgh <fubar@us.ibm.com> Cc: "David S.
