PCI: output FW warning in pci_read/write_vpd
pci_read/write_vpd() can fail due to a timeout. Usually the command
times out because of firmware issues (incorrect vpd length, etc.) on the
PCI card. Currently, the timeout occurs silently.
Output a message to the user indicating that they should check with
their vendor for new firmware.
