net: dl2k: switch from 'pci_' to 'dma_' API

Browse source 
[ Upstream commit b49db89e9697ddfa7fbe7387e176072ee2feb2db ]

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 in 'rio_probe1()' GFP_KERNEL can be used because
it is a probe function and no lock is taken in the between.
