ide: pci: free PCI BARs on initialization failure
Recent pci_assign_irq() changes uncovered a problem with missing freeing of
PCI BARs on PCI IDE host initialization failure:
ide0: disabled, no IRQ
ide0: failed to initialize IDE interface
ide0: disabling port
cmd64x 0000:00:02.0: IDE controller (0x1095:0x0646 rev 0x07)
CMD64x_IDE 0000:00:02.0: BAR 0: can't reserve [io 0x8050-0x8057]
cmd64x 0000:00:02.0: can't reserve resources
CMD64x_IDE: probe of 0000:00:02.0 failed with error -16
Fix the problem by adding missing freeing of PCI BARs to
ide_setup_pci_controller() and ide_pci_init_two().
Fixes: 30fdfb929e82 ("PCI: Add a call to pci_assign_irq() in pci_device_probe()")
Fixes: 0e4c2eeb758a ("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping hooks")
