powerpc/spufs: Fix multiple get_spu_context()
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(). Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
