The wrappers in include/linux/pci-dma-compat.h should go away.
Replace 'pci_set_dma_mask/pci_set_consistent_dma_mask' by an equivalent
and less verbose 'dma_set_mask_and_coherent()' call.

If needed, see post from Christoph Hellwig on the kernel-janitors ML:
https://marc.info/?l=kernel-janitors&m=158745678307186&w=4
We could also reduce indentation by merging the 2 'if' together. If this
is the preferred style, I'll send a v2.

If an error occurs after a 'adf_enable_aer()' call, it must be undone by a
corresponding 'adf_disable_aer()' call, as already done in the remove
function.
