[PATCH] enic: Remove usage of the deprecated "pci-dma-compat.h" API

[Christophe JAILLET]

In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation
Only relevant parts are given below.
