[LTP] [PATCH v3 1/1] aio-stress.c: Remove useless iteration variable

[Petr Vorel]

local iteration variable in worker() was probably left over from
previous version before rewrite because clang correctly reported also on
this old version:

    aio-stress.c:1049:6: warning: variable 'iteration' set but not used [-Wunused-but-set-variable]
    int iteration = 0;

NOTE: restart label was considered to be removed, but in the end kept.

Signed-off-by: Petr Vorel <pvorel@suse.cz>

Changes v2->v3:
* Keep restart label (remove only the variable)
