drivers:net: dma_alloc_coherent: use __GFP_ZERO instead of memset(, 0)
Reduce the number of calls required to alloc
a zeroed block of memory.
Trivially reduces overall object size.
Other changes around these removals
o Neaten call argument alignment
o Remove an unnecessary OOM message after dma_alloc_coherent failure
o Remove unnecessary gfp_t stack variable
