    fortran: Fix up hash table usage in gfc_trans_use_stmts [PR108451]

    The first testcase in the PR (which I haven't included in the patch bec=
ause
    it is unclear to me if it is supposed to be valid or not) ICEs since ex=
tra
    hash table checking has been added recently.  The problem is that
    gfc_trans_use_stmts does
              tree *slot =3D entry->decls->find_slot_with_hash (rent->use_n=
ame,
hash,
                                                              INSERT);
              if (*slot =3D=3D NULL)
    and later on doesn't store anything into *slot and continues.  Another =
spot
    a few lines later correctly clears the slot if it decides not to use the
    slot, so the following patch does the same.
