eccdata: (ecc_curve_init_str): Delete unused t and d arguments.

Related to the the edwards_root member of struct ecc_curve, which
was used by ecc_a_to_eh before it was deleted, see 2014-09-17
entry below.
(ecc_curve_init): Delete corresponding curve25519 constants, and
NULL arguments passed for the other curves.
