Fix: guard against potential overflow in file size calculation
The block_count is a size_t, so on 32 bit platforms the multiplication might be truncated before the comparison with filesz. On 64 bit platforms, it could potentially also overflow the 64 bit bounds of the data type. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
