dm log userspace base: fix compile warning
This fixes up a compile warning [-Wunused-but-set-variable] - given the comment in userspace_set_region_sync() the non-reporting of errors is intentional so the return value can be dropped to make gcc happy. Also, fix typo in comment. Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
