IB/mthca: Factor out setting WQE UD segment entries
Factor code to set UD entries out of the work request posting functions into inline functions set_tavor_ud_seg() and set_arbel_ud_seg(). This doesn't change the generated code in any significant way, and makes the source easier on the eyes. Signed-off-by: Roland Dreier <rolandd@cisco.com>
