net: stmmac: Restrict warning on disabling DMA store and fwd mode
commit 05d7623a892a9da62da0e714428e38f09e4a64d8 upstream.
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.")
