A user can write arbitrary integer values to msgmni and shmmni sysctl
parameters without getting error, but the actual limit is really
IPCMNI (32k). This can mislead users as they think they can get a
value that is not real.

The right limits are now set for msgmni and shmmni so that the users
will become aware if they set a value outside of the acceptable range.
