Jon Hunter reported observing a build bug in the IPA driver:
https://lore.kernel.org/netdev/5b5d9d40-94d5-5dad-b861-fd9bef826...@nvidia.com
The problem is that the QMB0 max read value set for IPA v4.5 (16) is
too large to fit in the 4-bit field.
This is a quick fix to resolve the build bug; this might change
again in the future if I learn there is a better value to use.
