SystemRedundancy firmware can establish 2 non-SR IO ARs, even if taglist disables SharedDevice

When using SystemRedundancy firmware, the taglist parameter "bNumAdditionalIOAR" does not work as expected.

According to it's definition: "Setting this parameter to 0 still allows using S2 redundancy with 2 redundant IO-Controllers. Shared Device with 2 non-redundant IO Controllers is not supported in this case. This represents an IO Device supporting S2 redundancy but without Shared Device."

However, if set to 0, the IO Device firmware still accepts 2 IO ARs.

Performing the same test with a non-SystemRedundancy firmware shows expected behavior.
