    xlators/io-stats: Coverity Fix CHECKED_RETURN in resolve_group_name

    Issue: Calling "getgrgid_r(gid, &grp, grp_buf, grp_buf_len, &grp_result)"
    without checking return value. This library function may fail and return
    an error code

    Solution: getgrgrid_r returns zero when the operation is successful
    and a non-zero error code if there's some error in the operation

    Fix: Checked for the return value and redirected to error if the
    return value was non-zero
