ethernet: remove redundant memset
kvzalloc already zeroes the memory during the allocation. pci_alloc_consistent calls dma_alloc_coherent directly. In commit 518a2f1925c3 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So the memset after these function is not needed.
