Claudio Imbrenda 6ae67dcac7 KVM: s390: Fix possible reference leak in fault-in code 
If kvm_s390_new_mmu_cache() fails, kvm_s390_faultin_gfn() returns
without releasing the faulted page.

Fix this by moving the allocation of the memory cache outside of the
loop. There is no reason to check at every iteration.

Opportunistically fix a comment.
