[PATCH -next 12/26] intel: Use dma_zalloc_coherent

From: Joe Perches <joe@perches.com>

Also in: lkml
Subsystem: intel ethernet drivers, networking drivers, the rest · Maintainers: Tony Nguyen, Przemek Kitszel, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

Use the zeroing function instead of dma_alloc_coherent & memset(,0,)
