Subject: [PATCH 81/87] ethernet: ti: remove memset after pci_alloc_persistent

pci_alloc_persistent 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.
