Prevent deadlock by basing DummyWaker directly on RawWaker
...
Don't use Arc for DummyWaker. It causes a drop in the `add_scancode` function, which can easily lead to a deadlock because the function is called directly from the interrupt handler.

Double Faults: A missing handler leads to a #GP exception (not a #NP)
...
A IDT entry that is zero is not valid (e.g. the must-be-one bits are not set). For this reason, a general protection fault occurs instead of a segment-not-present fault.
See https://github.com/phil-opp/blog_os/issues/449#issuecomment-558906316 for more information.
