bug fix

Description:
During the process of the combination of collective chunk IO code and the original IO code,
The return value of a function call hasn't been initialized. On 32-bit mode at modi4, that value isn't set to 0 by default. So a fake error value returns.

Solution:
Re-arrange the code so that the return value will be set properly.


Platforms tested:
parallel:
modi4 - 32bit
heping
seq:
heping
