staging: fieldbus: anybus-s: fix wait_for_completion_timeout return handling
wait_for_completion_timeout() returns unsigned long (0 on timeout or
remaining jiffies) not int. Assigning this return value to int may
theoretically overflow (though not in this case where TIMEOUT is
only HZ*2).
Fix this inconsistency by wrapping the wait_for_completion_timeout
into the if().
