KVM: MMU: increase per-vcpu rmap cache alloc size
The page fault path can use two rmap_desc structures, if:
- walk_addr's dirty pte update allocates one rmap_desc.
- mmu_lock is dropped, sptes are zapped resulting in rmap_desc being
freed.
- fetch->mmu_set_spte allocates another rmap_desc.
Increase to 4 for safety.
