commit 08771bce330036d473be6ce851cd00bcd351ebf6 upstream.

An incorrect NVM update procedure can result in the driver failing probe.
In this case, the recommended resolution method is to update the NVM
using the right procedure. However, if the driver fails probe, the user
will not be able to update the NVM. So do not fail probe on link/PHY
errors.
