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.
