IPC/shared memory: introduce shmctl_down
Currently, the way the different commands are handled in sys_shmctl introduces
some duplicated code.
This patch introduces the shmctl_down function to handle all the commands
requiring the rwmutex to be taken in write mode (ie IPC_SET and IPC_RMID for
now). It is the equivalent function of semctl_down for shared memory.
This removes some duplicated code for handling these both commands and
harmonizes the way they are handled among all IPCs.
