When reviewing #13875, I noticed that our FreeBSD code has an issue where it converts from `int64_t` to `int` when calling `vnlru_free{,_vfsops}()`. The result is that if the int64_t is `1 << 36`, the int will be 0, since the low bits are 0. Even when some low bits are set, a value such as `((1 << 36) + 1)` would truncate to 1, which is wrong. There is protection against this on 32-bit platforms, but on 64-bit platforms, there is no check to protect us, so we add a check.
