sh: Fix sh4a llsc-based cmpxchg()
This fixes up a typo in the ll/sc based cmpxchg code which apparently wasn't getting a lot of testing due to the swapped old/new pair. With that fixed up, the ll/sc code also starts using it and provides its own atomic_add_unless(). Signed-off-by: Aoi Shinkai <shinkoi2005@gmail.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
