vdso/timens: Always provide arch_get_vdso_data() prototype for vdso
The arch_get_vdso_data() function is defined separately on each architecture,
but only called when CONFIG_TIME_NS is set. If the definition is a global
function, this causes a W=1 warning without TIME_NS:
arch/x86/entry/vdso/vma.c:35:19: error: no previous prototype for 'arch_get_vdso_data' [-Werror=missing-prototypes]
Move the prototype out of the #ifdef block to reliably turn off that
warning.
