I would actually prefer to see providers updated to set this
explicitly.  Right now the rule is ib_alloc_device() returns a
completely zeroed out structure -- that's much easier to understand
than initializing some fields but not others.  And there are other
fields we could set defaults for, like phys_port_cnt == 0 is not legal
either, but we don't try to set that in the core.
