Richard Yao ae7e700650 Suppress static analyzer warning in dmu_objset_create_impl_dnstats() 
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.
