[Qemu-devel] [PATCH v2 1/6] pci: Clean up error checking in pci_add_capability() |

On success, pci_add_capability2() returns a positive value. On
failure, it sets an error and return a negative value.
pci_add_capability() laboriously checks this behavior. No other
caller does. Drop the checks from pci_add_capability().
