x86: kvm: remove useless calls to kvm_para_available
Most code in arch/x86/kernel/kvm.c is called through x86_hyper_kvm, and thus only runs if KVM has been detected. There is no need to check again for the CPUID base. Cc: Sergio Lopez <slp@redhat.com> Cc: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
