Make `missing_fragment_specifier` an unconditional error

This was attempted in [1] then reverted in [2] because of fallout.
Recently, this was made an edition-dependent error in [3].

Make missing fragment specifiers an unconditional error again.

[1]: https://github.com/rust-lang/rust/pull/75516
[2]: https://github.com/rust-lang/rust/pull/80210
[3]: https://github.com/rust-lang/rust/pull/128006
