[U-Boot] [PATCH 08/11] scsi: make the LUN a parameter of scsi_detect_dev()

[Jean-Jacques Hiblot]

This is a cosmetic change. target and LUN have kind of the same role in
this function. One of them was passed as a parameter and the other was
embedded in a structure. For consistency, pass both of them as parameters.
