ipc,msg: introduce msgctl_nolock
commit 2cafed30f150f7314f98717b372df8173516cae0 upstream.
Similar to semctl, when calling msgctl, the *_INFO and *_STAT commands
can be performed without acquiring the ipc object.
Add a msgctl_nolock() function and move the logic of *_INFO and *_STAT
out of msgctl(). This change still takes the lock and it will be
properly lockless in the next patch
