In IBM Power servers, when hardware error occurs during probe
state, EEH subsystem will call driver's error_detected interface,
which will call pci_disable_device(). But driver's probe function

The can_queue in scsi_host can be more than ATA_MAX_QUEUE (32),
for example, in ipr, it can be 100 or more.
Also, some drivers, like ipr driver, haven't filled the field
scsi_host in ata_port, and will lead a call trace, so add
check for that.

In pnv_pci_read_config() or pnv_pci_write_config(), we never check if
the PCI controller is valid before converting that into platform
dependent one, this is very dangerous.
To avoid this potential risks, the patch check PCI controller first
before use it.
