From: Thomas Gleixner <tglx@linutronix.de>

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.

Fixes: f86fd32db706 ("lib/vdso: Cleanup clock mode storage leftovers")
