KVM: Fix out of range accesses to memslots
Reset the LRU slot if it becomes invalid when deleting a memslot to fix
an out-of-bounds/use-after-free access when searching through memslots.
Explicitly check for there being no used slots in search_memslots(), and
in the caller of s390's approximation variant.
Fixes: 36947254e5f9 ("KVM: Dynamically size memslot array based on number of used slots")
