drivers:net: Convert dma_alloc_coherent(...__GFP_ZERO) to dma_zalloc_coherent
__GFP_ZERO is an uncommon flag and perhaps is better not used. static inline dma_zalloc_coherent exists so convert the uses of dma_alloc_coherent with __GFP_ZERO to the more common kernel style with zalloc. Remove memset from the static inline dma_zalloc_coherent and add just one use of __GFP_ZERO instead. Trivially reduces the size of the existing uses of dma_zalloc_coherent. Realign arguments as appropriate.
