x86/speculation: Simplify sysfs report of VMX L1TF vulnerability
Three changes to the content of the sysfs file:
- If EPT is disabled, L1TF cannot be exploited even across threads on the
same core, and SMT is irrelevant.
- If mitigation is completely disabled, and SMT is enabled, print "vulnerable"
instead of "vulnerable, SMT vulnerable"
- Reorder the two parts so that the main vulnerability state comes first
and the detail on SMT is second.
