IPC/message queues: introduce msgctl_down
Currently, sys_msgctl is not easy to read.
This patch tries to improve that by introducing the msgctl_down function to
handle all 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 message queues.
This greatly changes the readability of sys_msgctl and also harmonizes the way
these commands are handled among all IPCs.
