PCI: Handle error return from pci_reset_bridge_secondary_bus()

Browse Source 
Commit 01fd61c0b9 ("PCI: Add a return type for
pci_reset_bridge_secondary_bus()") added a return value to the function to
return if a device is accessible following a reset.  Callers are not
checking the value.

Pass error code up high in the stack if device is not accessible.

Fixes: 01fd61c0b9 ("PCI: Add a return type for pci_reset_bridge_secondary_bus()")
