KVM: PPC: Book3S HV: Add missing HPTE unlock

In kvm_test_clear_dirty(), if we find an invalid HPTE we move on to the
next HPTE without unlocking the invalid one.  In fact we should never
find an invalid and unlocked HPTE in the rmap chain, but for robustness
we should unlock it.  This adds the missing unlock.
