npu2-opencapi: reduce number of retries to train the link
We've been reliably training the opencapi link on the first attempt
for quite a while. Furthermore, if it doesn't train on the first
attempt, retries haven't been that useful. So let's reduce the number
of attempts we do to train the link.
2 retries = 3 attempts to train.
Each (failed) training sequence costs about 3 seconds.
