The cntvct_ok variable has not had any external user since commit
c7a18100bd ("lib/vdso: Avoid highres update if clocksource is not
VDSO capable").
It also only has one user in vdso.c, once during init, so rather than
having the caller of patch_vdso() initialize cntvct_ok, just call
cntvct_functional() directly and avoid the global variable entirely.
