[PATCH -perfbook] future/htm: Remove ref to Tabel 17.3 in QQ

[Akira Yokosawa]

Table 17.3 is not available in EBook-size builds.
For compatibility, remove reference to the combined table in Quick
Quiz added in commit 279c38a988f9 ("future/htm: Add some HTM
hardware-reliability anecdotes").

Fixes: 279c38a988f9 ("future/htm: Add some HTM hardware-reliability anecdotes")

Hi Paul,

Current master fails to build "eb".
I think reference to Table 17.3 is not essential to the Quick Quiz
and just removed it.
If you think otherwise, it can be made conditional by \IfEbookSize{}{}.

        Thanks, Akira

PS: As for hardware implementation of transactional memory,
Power ISA v3.1 deprecated it [1].
It might be worth mentioning it in the Answer to the QQ.
In the post specter world, it looks like almost impossible for hardware
designers to come up with a secure implementation of HTM...

Thank you for bringing this to my attention!  I have added it in
with your Suggested-by.

							Thanx, Paul
