Jia-Ju Bai 640f93cc6e i40e: Fix a sleep-in-atomic bug 
The driver may sleep under a spin lock, and the function call path is:
i40e_ndo_set_vf_port_vlan (acquire the lock by spin_lock_bh)
  i40e_vsi_remove_pvid
    i40e_vlan_stripping_disable
      i40e_aq_update_vsi_params
        i40e_asq_send_command
          mutex_lock --> may sleep

To fixed it, the spin lock is released before "i40e_vsi_remove_pvid", and
the lock is acquired again after this function.
