IPC: consolidate sem_exit_ns(), msg_exit_ns() and shm_exit_ns()
sem_exit_ns(), msg_exit_ns() and shm_exit_ns() are all called when an
ipc_namespace is released to free all ipcs of each type. But in fact, they
do the same thing: they loop around all ipcs to free them individually by
calling a specific routine.
This patch proposes to consolidate this by introducing a common function,
free_ipcs(), that do the job. The specific routine to call on each
individual ipcs is passed as parameter. For this, these ipc-specific
'free' routines are reworked to take a generic 'struct ipc_perm' as
parameter.
