[PATCH] ipcsem: remove superflous decrease variable from sys_semtimedop

Hi Andrew,

Patrick noticed that the initial scan of the semaphore operations logs 
decrease and increase operations seperately, but then both cases are 
or'ed together and decrease is never used.
The attached patch removes the decrease parameter - it shrinks 
sys_semtimedop() by 56 bytes.
Could you add it to your tree?
