Non-PCI AHCI support is broken due to assertion failures when trying to convert AHCIState to a PCIDevice pointer as AHCIState can have different container structs. Fix this by using the non-asserting object cast and checking the returned pointer is not NULL. The AddressSpace pointer is also being initialized to NULL and causing dma_memory_map call to fail. Fix this by initializing to address_space_memory for sysbus instances. Also correct AHCI_VMSTATE to use the correct container SysbusAHCIState for sysbus instances.
