tar2sqfs: Fix integer truncation issue when appending data to a tarball
The data is processed 2G at a time to avoid this exact issue, but the check was skipped on 64 bit systems, since the function *used to* use size_t instead of sqfs_u32. This commit removes the second check. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
