Stop marking unit_queue

The original motivation of this marking was https://github.com/k0kubun/yarv-mjit/issues/20.
As wanabe said, there are multiple options to mitigate the issue, and
Eric Wong introduced another fix at 143776f6fe by checking unit->iseq
inside the lock.

Therefore this particular condition has been covered in two ways, and
the script given by wanabe no longer crashes without mjit_mark().
