Incorrect const in futex(2) example code

[rahl <rahl@xxxxxxxxxx>]

I noticed that 'const' is used for both 'one' and 'zero' variables in the Examples section demo code of manpage 'futex(2)'.

The variables are both used in calls to 'atomic_compare_exchange_strong()' where the 'const' is discarded as it may write to the 'expected' parameter during a "failure" case.

Attached is the trivial patch to remove the offending qualifiers.

Cheers
