zkey: Also check for deconfigured and check-stopped cards

Browse Source 
When checking if a card or an APQN is online, not only check the 'online'
sysfs attribute, but also check the 'config' and 'chkstop' attribute.
Cards and APQNs in check-stopped or deconfigured state can still be reported
as online via the sysfs attribute, although they are not available to be
used for zkey.

In case the 2 additional sysfs attributes are not available in sysfs, then
don't fail, but rely on the 'online' attribute only.
