x86/speculation: Simplify the CPU bug detection logic
commit 8ecc4979b1bd9c94168e6fc92960033b7a951336 upstream.
Only CPUs which speculate can speculate. Therefore, it seems prudent
to test for cpu_no_speculation first and only then determine whether
a specific speculating CPU is susceptible to store bypass speculation.
This is underlined by all CPUs currently listed in cpu_no_speculation
were present in cpu_no_spec_store_bypass as well.
