IB/rdmavt: Correct issues with read-mostly and send size cache lines
The s_ahgpsn was incorrectly placed in the read-mostly section of the QP and the s_curr_size and s_hdrwords are oversized. The misplaced s_ahgpsn will cause the read-mostly cachelines to thrash. Place s_ahgpsn in the send side cache lines and correctly size and s_hdrwords and s_cur_size to keep the send side cachelines at the same size.
