Fairly straightforward conversions in all spots. In a couple of cases
any error gets propogated up should sg_map fail. In other
cases a warning is issued if the kmap fails seeing there's no
clear error path. This should not be an issue until someone tries to
use unmappable memory in the sgl with this driver.
