iw_cxgb4: invalidate the mr when posting a read_w_inv wr
Also, rearrange things a bit to have a common c4iw_invalidate_mr() function used everywhere that we need to invalidate. Fixes: 49b53a93a64a ("iw_cxgb4: add fast-path for small REG_MR operations") Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
