lszcrypt: fix random domain printout when no config available
lszcrypt: fix random domain printout when no config available

The sysfs files ap_control_domain_mask and ap_usage_domain_mask
may hold just a string "not supported" if there's no crypto
configuration available. However, lszcrypt always processed
the content of these files as hex number and so produced funny
output if there's no configuration data available.
