commit c7f3d43b629b598a2bb9ec3524e844eae7492e7e upstream.
CONFIG_GENERIC_VDSO_CLOCK_MODE was a transitional config switch which got removed after all architectures got converted to the new storage model.
But the removal forgot to remove the #ifdef which guards the vdso_clock_mode sanity check, which effectively disables the sanity check.
Remove it now.
