hdb/hdb-mitdb: Nix unused variable key_data in mdb_seq.

Browse Source 
key_data is unused.  Presumably this was copypasta from DB_seq in
hdb/db.c, where it is used for the Heimdal database format in which
the value may be missing a principal but it can be recovered from the
key.  In contrast, the mit-krb5 format appears to always store the
principal in the value and _hdb_mdb_value2entry always retrieves it,
with no need for a key2principal fallback.
