Borislav Petkov (AMD) 9080f4fcc2 x86/srso: Correct the mitigation status when SMT is disabled 
commit 6405b72e8d17bd1875a56ae52d23ec3cd51b9d66 upstream.

Specify how is SRSO mitigated when SMT is disabled. Also, correct the
SMT check for that.

Fixes: e9fbc47b818b ("x86/srso: Disable the mitigation on unaffected configurations")
