actually, I prefer to keep these little helpers. I was recently playing
with adding SG list support to g_zero (I should have patches soon) and
it was actually very nice to have the sourcesink helper as I could just
ditch alloc_ep_req(). The change to the driver was local to
ss_alloc_ep_req() and nothing else changed :-)
