Clang's static analyzer claims that dereferencing ds in dmu_objset_create_impl_dnstats() could cause a NULL pointer dereference when a previous NULL check confirms that it is NULL. It is only NULL on the MOS, for which dmu_objset_userused_enabled(os) should always return false, so ds will never be dereferenced when it is NULL. We add an assertion to suppress this warning.
