IPC/semaphores: move the rwmutex handling inside semctl_down
semctl_down is called with the rwmutex (the one which protects the list of
ipcs) taken in write mode.
This patch moves this rwmutex taken in write-mode inside semctl_down.
This has the advantages of reducing a little bit the window during which this
rwmutex is taken, clarifying sys_semctl, and finally of having a coherent
behaviour with [shm|msg]ctl_down
