[PATCH RESEND v3 01/10] pci: pass along the return value of dma_memory_rw

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

From: Klaus Jensen <k.jensen@samsung.com>

Some might actually care about the return value of dma_memory_rw. So
let us pass it along instead of ignoring it.

There are no existing users of the return value, so this patch should be
safe.
