sh: fixed cmpxchg gRB version
This patch fixes a bug within the cmpxchg GRB version.
A problem was notices while running some tests to stress
the priority inheritance, for example pi_stress
(http://rt.wiki.kernel.org/index.php/PI_Mutex_Test).
Also, without this patch, after applying the latest work to
consolidate atomic_cmpxchg() definitions (commit:
8c0b8139c87cfe8b95c6e763b4ca3190aa9b1ad0)
the Kernel doesn't boot at all.
