[PATCH net] net: ethernet: microchip: lan743x: Fix memory allocation failure

[Thangaraj Samynathan]

The driver allocates ring elements using GFP_ATOMIC and GFP_DMA
flags. The allocation is not done in atomic context and there is
no dependency from LAN743x hardware on memory allocation should be
in DMA_ZONE. Hence modifying the flags to use only GFP_KERNEL.
