The adios_close () does not return value

[yomagg]

The function has the protytype:

int adios_close (int64_t fd_p);

The retval is initialized with common_adios_close() but from what I can see it is never returned by adios_close(). Simply put, the return retval; is missing.

Fixed. Now every int function returns 0 on OK, !=0 on error (values in adios_error.h).
