skd: use ktime_get_real_seconds()
Like many storage drivers, skd uses an unsigned 32-bit number for interchanging the current time with the firmware. This will overflow in y2106 and is otherwise safe. However, the get_seconds() function is generally considered deprecated since the behavior is different between 32-bit and 64-bit architectures, and using it may indicate a bigger problem. To annotate that we've thought about this, let's add a comment here and migrate to the ktime_get_real_seconds() function that consistently returns a 64-bit number.
