is switched to (software) offline. If a card is 'deconfigured' via
HMC, SE or chzcrypt the field shows 'deconfig'.

A crypto card may also reach a 'checkstopped' state. lszcrypt shows
this as 'chkstop'.

If a queue is not bound to a device driver there is no detailed
information available and thus the status shows only '-'.
