The current test_qp_ex_rc_bind_mw in tests/test_qpex.py uses an incorrect
value for the new_rkey based on the old mr.rkey. This patch fixes that
behavior by basing the new rkey on the old mw.rkey instead.
Before this patch the test will fail for the rxe driver about 1 in 256
tries since randomly that is the freguency of new_rkeys which have the
same 8 bit key portion as the current mw which is not allowed. With
this patch those errors do not occur.
