beam_ssa_pre_codegen: Remove unreachable code

Remove handling of an annotation for `match_fail` that have neither
`location` nor `inlined`. At least by compiling Erlang code, it should
be impossible to have both of those missing. When compiling from Core
Erlang code, it also seems impossible or hard to have both missing,
since the compiler makes its best to add an `inlined` annotation.
