Eric Dumazet d3694f3073 dma-debug: reorder struct dma_debug_entry fields 
Move all fields used during exact match lookups to the first cache line.
This makes debug_dma_mapping_error() and friends about 50% faster.

Since it removes two 32bit holes, force a cacheline alignment on struct
dma_debug_entry.
