Conrad Meyer fadd3f8a66 pci_ioctl: Avoid returning uninitialized error value if user provided empty buffer
In the weird case where the user-provided buffer was zero bytes, we could break
out of PCIOCGETCONF and return without initializing error.  In this case,
initialize error to zero -- we successfully did nothing, as requested.
