Normalize SC_ERROR_* API and clean up ISO7816-4 errors.

 * iso7816_check_sw() emits a "informational message" (from ISO7816-4 table 6)
 * SW-s which are not known or not meaningful for internal API get translated
   to SC_ERROR_CARD_CMD_FAILED by default, so use it also in the SW table
 * Remove undefined SW-s and move generic SW-s to their sequential location.
