KVM: MMU: drop zeroing on mmu_memory_cache_alloc

Zeroing on mmu_memory_cache_alloc is unnecessary since:

- Smaller areas are pre-allocated with kmem_cache_zalloc.
- Page pointed by ->spt is overwritten with prefetch_page and entries in page pointed by ->gfns are initialized before reading.

Applied, thanks.
