Subject: dma: use ERROR_INT()

The first in a series excising the use of the "return -errno" idiom. This is a
non-standard usage, and in userspace, we have "errno" for delivering side-band
error values. As there have been multiple bugs from not using standard error
return methods like -1+errno or NULL+errno, let's do that.
