ipc: fix unused variable warning
Commit a0d092f introduced the following warning: ipc/msg.c: In function ?msgctl_down?: ipc/msg.c:415: warning: ?msqid64? may be used uninitialized in this function The gcc warning in this case is actually bogus, as msqid64 is touched only iff cmd == IPC_SET, and in such case, copy_msqid_from_user() initializes it properly.
