When setting 'snps,force_thresh_dma_mode' DT property, the following warning is always emitted, regardless the status of force_sf_dma_mode: dwmac-starfive 10020000.ethernet: force_sf_dma_mode is ignored if force_thresh_dma_mode is set. Do not print the rather misleading message when DMA store and forward mode is already disabled. Fixes: e2a240c7d3bc ("driver:net:stmmac: Disable DMA store and forward mode if platform data force_thresh_dma_mode is set.")
