[PATCH 37/87] ethernet: atlx: remove memset after pci_alloc_consistent in atl1.c

[Fuqian Huang]

pci_alloc_consistent calls dma_alloc_coherent directly.
In commit af7ddd8a627c
("Merge tag 'dma-mapping-4.21' of git://git.infradead.org/users/hch/dma-mapping"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
