Claudio Imbrenda d8dfda5af0 KVM: s390: pv: fix race when making a page secure 
Holding the pte lock for the page that is being converted to secure is
needed to avoid races. A previous commit removed the locking, which
caused issues. Fix by locking the pte again.

Fixes: 5cbe24350b ("KVM: s390: move pv gmap functions into kvm")
