s390/ipl: Fix detection of has_secure attribute
Use the correct bit for detection of the machine capability associated
with the has_secure attribute. It is expected that the underlying
platform (including hypervisors) unsets the bit when they don't provide
secure ipl for their guests.
Fixes: c9896acc7851 ("s390/ipl: Provide has_secure sysfs attribute")
