dm log: use PTR_ERR value instead of ENOMEM
It's nicer to return the PTR_ERR() value instead of just returning -ENOMEM. In the current code the PTR_ERR() value is always equal to -ENOMEM so this doesn't actually affect anything, but still... In addition, dm_dirty_log_create() doesn't check for a specific -ENOMEM return. So this change is safe relative to potential for a non -ENOMEM return in the future.
