[ Upstream commit 503234b3fdcaa578395c07e393ea3e5d13958824 ]
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")
