The previous patch 4130055c went a bit too
far in it's mission to reorder events, and included putting HSH_Fail()
after ObjSetState(). That caused problems for code looking at the
OC_F_FAILED to learn about failed fetches.

Change the order of this back to normal, and move the call to HSH_Fail()
into ObjSetState(), so that the order can be shown and the caveats
properly commented.
