[PATCH] msgsnd(2): msg_bytes -> msg_qbytes

[Michael Witten <mfwitten-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Mihail Paraschivescu <paraschivescu_mihail-/E1597aS9LQAvxtiuMwx3w@public.gmane.org> reported
here:

    http://marc.info/?l=linux-man&m=127160667709342&w=2
    http://www.spinics.net/lists/linux-man/msg01271.html

the following:

    "The queue capacity is defined by the msg_bytes field in
    the associated data structure for the message queue."

    If I'm not wrong, the exact name of that field in the
    msqid_ds structure is msg_qbytes. The same thing appears
    also on the online [POSIX] manual pages, I checked it
    already.

I provided a detailed confirmation with quotes from the
Linux kernel sources:

    http://www.spinics.net/lists/linux-man/msg01273.html

This patch (requested by Mihail) makes the correction and
removes unnecessary implementation details.
