Changing the SO-PIN using pkcs11-tool fails with CKR_PIN_LEN_RANGE after the maximum length of the user PIN was reduced from 16 to 15.

The bug can be verified with

./pkcs11-tool --module ../pkcs11/.libs/opensc-pkcs11.so --login --login-type so --so-pin 3537363231383830 --change-pin --new-pin 3537363231383830

Apparently pkcs15_change_pin() in framework-pkcs15.c picks the wrong auth object. It seems like it always picks the first (User PIN) object rather than the SO-PIN object. Because the SO-PIN is (min=16/max=16) and the PIN is now (min=6/max=15) the call fails.
