gpg: Fix warnings about useless assignments.

Browse Source 
* g10/armor.c (parse_hash_header): Remove duplicate var assignment.
* g10/getkey.c (cache_user_id): Ditto.
* g10/keygen.c (ask_curve): Ditto.  This also fixes a small memory
leak.

* g10/keygen.c (proc_parameter_file): Remove useless assignment or
pointer increment.
(generate_keypair): Ditto.
* g10/getkey.c (finish_lookup, lookup): Ditto.
* g10/card-util.c (change_pin): Ditto.
* g10/gpg.c (main) <aVerify>: Ditto.
* g10/import.c (import): Ditto.
(print_import_check): Ditto
* g10/keyring.c (do_copy): Ditto.
* g10/tdbio.c (tdbio_read_record): Ditto.
* g10/trustdb.c (tdb_update_ownertrust): Ditto.
(update_validity): Ditto.

* g10/server.c (cmd_passwd): Remove useless call to skip_options.
