net: lan743x: Allocate rings outside ZONE_DMA
The driver allocates ring elements using GFP_DMA flags. There is
no dependency from LAN743x hardware on memory allocation should be
in DMA_ZONE. Hence modifying the flags to use only GFP_ATOMIC. This
is consistent with other callers of lan743x_rx_init_ring_element().
