scsi: message: fusion: Remove usage of the deprecated "pci-dma-compat.h" API

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.  It
can be found in [3].

In this patch, all functions but pci_alloc_consistent() are handled.
pci_alloc_consistent() needs more attention and explanation.
