x86_machine_is_smm_enabled() checks the KVM_CAP_X86_SMM for KVM
case. No need to check KVM_CAP_X86_SMM specifically.

One benefit of checking it specifically is that it can return early when
KVM_CAP_X86_SMM is not supported. But considering KVM_CAP_X86_SMM was
added in KVM 10 year ago, it's unlikely the case.

So just drop the check of KVM_CAP_X86_SMM to simplify the code.
