s390/dasd: fix read unit address configuration loop
Read unit address is done for all devices during online processing to read
out LCU features. This is also done after disconnect/connect a LCU.
Some older storage hardware does not provide the capability to read unit
address configuration.
This leads to a loop trying to read unit address configuration every 30
seconds. The device is still operational but logs are flooded with error
messages.
Fix the loop by recognizing a command reject saying that the suborder
for ruac is not supported.
