KVM: s390: pv: usage counter instead of flag
Use the new protected_count field as a counter instead of the old
is_protected flag. This will be used in upcoming patches.
Increment the counter when a secure configuration is created, and
decrement it when it is destroyed. Previously the flag was set when the
set secure parameters UVC was performed.
