ucm: using UD type QP's, ucm reports wrong reject event when user rejects AH resolution request.

During rejects, both usr and ucm internal, the qp_type does not get initialized
so the check for UD type QP messages fail on active side and the wrong
event gets generated. Initialize saddr.ib information before sending reject
back to active side.
