This partially reverts 4804febd.
The commit introduced a constant-time protection when interpolating the library state (HAVE_LIB_ERROR) in the return code. In _wrap_nettle_pk_decrypt2, however, the library state can only be modified by rnd_nonce_func for RSA blinding, which is calculated sorely from the public values. Therefore, we do not need to worry about constant timeness in that logic.
