c8e424c9 (hashmap: introduce hashmap_free_entries, 2019-10-06)
introduced hashmap_free_entries(), which can free any struct pointer,
regardless of the hashmap_entry field offset.

oidmap does not make use of this flexibilty, hardcoding the offset to
zero instead. Let's fix this by passing struct type and member to
hashmap_free_entries().

Additionally, remove an erroneous semi-colon at the end of
hashmap_free_entries() macro.
