KVM: x86: Do not use kvm_x86_ops->mpx_supported() directly
Commit a87036add092 ("KVM: x86: disable MPX if host did not enable MPX XSAVE features") introduced kvm_mpx_supported() to return true iff MPX is enabled in the host. However, that commit seems to have missed replacing some calls to kvm_x86_ops->mpx_supported() to kvm_mpx_supported(). Complete original commit by replacing remaining calls to kvm_mpx_supported(). Fixes: a87036add092 ("KVM: x86: disable MPX if host did not enable MPX XSAVE features") Suggested-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Liran Alon <liran.alon@oracle.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
