[MIPS] Fix bug in atomic_sub_if_positive.
The branch optimization fixes in 2.6.21 introduced a bug in
atomic_sub_if_positive that causes it to return even when the sc
instruction fails. The result is that e.g. down_trylock becomes unreliable
as the semaphore counter is not always decremented.
Original MUA-shredded patch from Morten Larsen <mlarsen@broadcom.com>.
