powerpc/spufs: Fix multiple get_spu_context()

Browse Source 
Commit 8d5636fbca202f61fdb808fc9e20c0142291d802 introduced a reference
count on SPU contexts during find_victim, but this may cause a leak in
the reference count if we later find a better contender for a context to
unschedule.

Change the reference to after we've found our victim context, so we
don't do the extra get_spu_context().
