Marko Mäkelä 021652ba50 MDEV-15872 Crash in online ALTER TABLE...ADD PRIMARY KEY after instant ADD COLUMN...NULL ...

row_log_table_get_pk_col(): Replace a condition that was inadvertently
removed in MDEV-16365. PRIMARY KEY columns are never allowed to be NULL,
and failure to enforce the constraint caused a null pointer to be
dereferenced in mem_heap_dup().
