KVM: Really remove a slot when a user ask us so
Right now, KVM does not remove a slot when we do a register ioctl for size 0 (would be the expected behaviour). Instead, we only mark it as empty, but keep all bitmaps and allocated data structures present. It completely nullifies our chances of reusing that same slot again for mapping a different piece of memory. In this patch, we destroy rmaps, and vfree() the pointers that used to hold the dirty bitmap, rmap and lpage_info structures.
