Validate OBUS DL lane failed indications during initial link training

Under certain circumstances, the DL logic can consume a spare lane
during training, reporting that the link trained successfully but without
reporting a lane sparing event in the FIR

This commit adds a change to check for failed lanes in this case, and:
- raise the lane spared indication in the FIR if a single lane is spared
  (no HWP error returned, but attention can trigger MFG IPL failure)
- mark the link as failed to train if more than a single lane is marked
  spared, to trigger reconfig loop
