[LTP] [PATCH 1/1] aio-stress.c: Use static variable iterations

[Petr Vorel]

local iteration variable in worker() was probably left over from
previous versions rewrite (maybe -i was not used in previous versions).

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

Fixes: 054d45390 ("Rewrite aio-stress test using LTP API")
