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.
