scsi: message: fusion: Use dma_alloc_coherent() in mpt_alloc_fw_memory() 

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].

mpt_alloc_fw_memory() should still use GFP_ATOMIC, because it can be called
from mpt_do_upload() which might sleep.
