    rdma/i40iw: hide high-order-allocation warning in i40iw_save_msix_info()
    
    Size of struct i40iw_msix_vector was increased in RHEL7.7 kernels
    due to ML commit 43731753c4b7 ("RDMA/i40iw: Avoid panic when reading back the
    IRQ affinity hint").
    It triggers high-order-allocation warning in i40iw_save_msix_info().
    
    The patch disables this warning.
