KVM: s390/mm: Fix page table locking vs. split pmd lock
commit ec66ad66a0de87866be347b5ecc83bd46427f53b (s390/mm: enable split page table lock for PMD level) activated the split pmd lock for s390. Turns out that we missed one place: We also have to take the pmd lock instead of the page table lock when we reallocate the page tables (==> changing entries in the PMD) during sie enablement.
