PCI: Use an error code with PCIe failed link retraining

Browse source

commit 59100eb248 upstream.

Given how the call place in pcie_wait_for_link_delay() got structured now,
and that pcie_retrain_link() returns a potentially useful error code,
convert pcie_failed_link_retrain() to return an error code rather than a
boolean status, fixing handling at the call site mentioned.  Update the
other call site accordingly.
