The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.

When memory is allocated, GFP_KERNEL can be used because it is called from
the probe function (i.e. 'fealnx_init_one()') and no lock is taken.
