Certainly umad is useful without uverbs.  For example one can use
just umad to run OpenSM.  In fact umad predates uverbs by quite a long
time.  Thanks for pointing this out -- certainly we don't want to lump
umad and uverbs into the same config option.

ucm and uat probably aren't that useful without uverbs.

So I guess the final patch should have CONFIG_INFINIBAND_USER_MAD and
CONFIG_INFINIBAND_USER_ACCESS as separate config options.
