LOAD POSITIVE instructions (LPR, LPGR and LPGFR) set the following
condition code:
   0: Result zero; no overflow
   1: --
   2: Result greater than zero; no overflow
   3: Overflow

The current code wrongly returns 1 instead of 2 in case of a result
greater than 0. This patches fixes that. This fixes the marshalling of
the value '0L' in Python.
