[ofw] typical values for ci_umv_buf_t

[Reuven Amitai]

IBAL calls uvp:post() in query_av verb even when the uvp:pre() returns
IB_VERBS_PROCESSING_DONE
in order to return pd (which absent in the pre() prototype)
I think there is no need for that in create_av verb.

I looked at the places where ibal checked for IB_VERBS_PROCESSING_DONE.
It's only done in a handful of calls: address vector routines, and query
CQ.

For the av calls, if uvp:pre() returns IB_VERBS_PROCESSING_DONE, then
ibal calls uvp:post().  (I don't get the need for this...)  For query
CQ, if uvp:pre() returns IB_VERBS_PROCESSING_DONE, ibal simply returns.
