utimes: Clamp the timestamps in notify_change()
commit eb31e2f63d85d1bec4f7b136f317e03c03db5503 upstream.
Push clamping timestamps into notify_change(), so in-kernel
callers like nfsd and overlayfs will get similar timestamp
set behavior as utimes.
AV: get rid of clamping in ->setattr() instances; we don't need
to bother with that there, with notify_change() doing normalization
in all cases now (it already did for implicit case, since current_time()
clamps).

Fixes: 42e729b9ddbb ("utimes: Clamp the timestamps before update")
