Keqian Zhu e0a8f99355 accel: kvm: Fix memory waste under mismatch page size ... When handle dirty log, we face qemu_real_host_page_size and TARGET_PAGE_SIZE. The first one is the granule of KVM dirty bitmap, and the second one is the granule of QEMU dirty bitmap. As qemu_real_host_page_size >= TARGET_PAGE_SIZE (kvm_init() enforced it), misuse TARGET_PAGE_SIZE to init kvmslot dirty_bmap may waste memory. For example, when qemu_real_host_page_size is 64K and TARGET_PAGE_SIZE is 4K, it wastes 93.75% (15/16) memory.
