Most callers of scsi_rescan_device() have the scsi_device pointer
available. Pass a struct scsi_device pointer to scsi_rescan_device()
instead of a struct device pointer. This change prevents that a
pointer to another struct device pointer would be passed accidentally to
scsi_rescan_device().
Remove the scsi_rescan_device() declaration from the scsi_priv.h header
file since it duplicates the declaration in <scsi/scsi_host.h>.
