vdso/gettimeofday: Rename __arch_get_vdso_u_timens_data()

Browse Source 
Originally this function was supposed to work the same way as
__arch_get_vdso_u_time_data() and be overridden on some architectures.
However the actually used implementation, which just adds PAGE_SIZE, does
not need this override mechanism.

Adjust the name to reflect the true nature of the function.
