target: Avoid integer overflow in se_dev_align_max_sectors()
The expression (max_sectors * block_size) might overflow a u32 (indeed, since iblock sets max_hw_sectors to UINT_MAX, it is guaranteed to overflow and end up with a much-too-small result in many common cases). Fix this by doing an equivalent calculation that doesn't require multiplication. While we're touching this code, avoid splitting a printk format across two lines and use pr_info(...) instead of printk(KERN_INFO ...).
