[PATCH 1/1] hamt: Fix coding errors.

["Marc Nieper-Wißkirchen" <marc.nieper+gnu@gmail.com>]

From: Marc Nieper-Wißkirchen <marc@nieper-wisskirchen.de>

Reported by Bruno Haible in
<https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00047.html>
after a Coverity run.
* lib/hamt.c (bucket_do_while, hamt_iterator): Add missing
derefencing operator and silence a bogus warning on uninitialized
variables.
* tests/test-hamt.c (test_general): Replace two errorneous
assignment operators with comparison operators.
