IB/rdmavt: Correct issues with read-mostly and send size cache lines

Browse source

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.
