sd-journal: fix memzero size in data hash table setup

Browse Source 
journal_file_setup_data_hash_table() allocates s * sizeof(HashItem)
bytes for the hash table but then only zeroes s bytes, leaving 15/16 of
the entries uninitialized. This corrupts the hash chain in any newly
created journal file.

The adjacent journal_file_setup_field_hash_table() already uses the
correct size.
