scd:openpgp: Pass arg ctrl to more functions.
* scd/app-openpgp.c (verify_a_chv): Add currently unused arg ctrl. Adjust callers. (verify_chv3): Ditto. (verify_chv2): Add arg ctrl. Adjust callers. (change_keyattr): Ditto. (change_rsa_keyattr): Ditto. (change_keyattr_from_string): Ditto. (rsa_writekey): Ditto. (ecc_writekey): Ditto. -- This helps in backporting from master.
