reftable: introduce `REFTABLE_FREE_AND_NULL()`
We have several calls to `FREE_AND_NULL()` in the reftable library, which of course uses free(3P). As the reftable allocators are pluggable we should rather call the reftable specific function, which is `reftable_free()`. Introduce a new macro `REFTABLE_FREE_AND_NULL()` and adapt the callsites accordingly. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
