net/mlx5_core,mlx5_ib: Do not use vmap() on coherent memory
As David Daney pointed in mlx4_core driver [1], mlx5_core is also
misusing the DMA-API.
This patch is removing the code that vmap() memory allocated by
dma_alloc_coherent().
After this patch, users of this drivers might fail allocating resources
on memory fragmeneted systems. This will be fixed later on.
