habanalabs: fix rc when new CPUCP opcodes are not supported

When the new CPUCP opcodes are not supported and a CPUCP packet fails,
the return value is the F/W error resposone which is a positive value.
If this packet is sent from IOCTL and the positive value is used, the
ICOTL will not be considered as unsuccessful.
