KVM: s390: cmma: Fix dirty tracking when removing memslot
When a memslot is removed, all ptes that mapped the slot are cleared or
even deallocated. If this happens while the system is in migration
mode, and if cmma-dirty pages are removed, the cmma-dirty counter will
not reflect reality.
Fix by appropriately decrementing the cmma-dirty counter when removing
a memslot.
Opportunistically improve kvm_arch_commit_memory_region() to use
__free() for the struct kvm_s390_mmu_cache.
