[S390] zcrypt: Do not remove coprocessor for error 8/72
In a case where the number of the input data is bigger than the modulus of the key, the coprocessor adapters will report an 8/72 error. This case is not caught yet, thus the adapter will be taken offline. To prevent this, we return an -EINVAL instead.
