MDEV-23566 SIGSEGV in mtr_t::init

Browse Source 
mtr_t::init(): Correct the debug assertion that was added in
commit c89366866bca2df46b0592719a1f6b6dabf470cb (MDEV-22970).
When the original failure scenario involves the system tablespace,
we could have m_user_space==nullptr. Let us compare m_user_space_id
instead.
