Alexey Kardashevskiy 193982c6f9 pci: Only unmap bus_master_enabled_region if was added previously ... Normally pci_init_bus_master() would be called either via bus->machine_done.notify or directly from do_pci_register_device(). However if a device's realize() failed, pci_init_bus_master() is not called, and do_pci_unregister_device() fails on memory_region_del_subregion() as it was not mapped. This adds a check that subregion was mapped before unmapping it.
