KVM: s390/mm: Fix page table locking vs. split pmd lock
commit 55e4283c3eb1d850893f645dd695c9c75d5fa1fc upstream.
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.
