tests: Don't assume structure of PCI IO base in ahci-test
In a couple of places ahci-test makes assumptions about how the tokens returned from qpci_iomap() are formatted in ways it probably shouldn't. First in verify_state() it uses a non-NULL token to indicate that the AHCI device has been enabled (part of enabling is to iomap()). This changes it to use an explicit 'enabled' flag instead. Second, it uses the fact that the token contains a PCI address, stored when the BAR is mapped during initialization to check that the BAR has the same value after a migration. This changes it to explicitly read the BAR register before and after the migration and compare. Together, these changes will make the test more robust against changes to the internals of the libqos PCI layer.
