> The PF driver state flag __I40E_VIRTCHNL_OP_PENDING needs to be
> checked and set at the beginning of i40e_ndo_set_vf_mac. Otherwise, if
> there are error conditions before it, the flag will be cleared unexpectedly by
> this function to cause potential race conditions.
> Hence move the check to the top of this function.
