IB/uverbs: Increase maximum devices supported
Some large systems may support more than IB_UVERBS_MAX_DEVICES
(currently 32).
This change allows us to support more devices in a backwards-compatible
manner. The first IB_UVERBS_MAX_DEVICES keep the same major/minor
device numbers that they've always had.
If there are more than IB_UVERBS_MAX_DEVICES, we then dynamically
request a new major device number (new minors start at 0).
This change increases the maximum number of HCAs to 64 (from 32).
