scsi: core: Pass the SCSI host pointer directly to scanning functions

In the functions scsi_probe_and_add_lun(), scsi_sequential_lun_scan(),
scsi_report_lun_scan() and __scsi_scan_target() the SCSI host pointer is
derived from the SCSI target pointer. Pass the SCSI host pointer
directly.

This patch prepares for enabling context analysis. With this patch applied,
context annotations can refer to the SCSI host pointer directly, e.g.
__must_hold(&shost->scan_mutex). Without this patch, the following
annotation would have to be used:
	__must_hold(&dev_to_shost(starget->dev.parent)->scan_mutex)
Additionally, in code that locks shost->scan_mutex, the following would
have to be added to help the compiler understand that shost ==
dev_to_shost(starget->dev.parent):
	__assume_ctx_lock(&dev_to_shost(starget->dev.parent)->scan_mutex);
__assume_ctx_lock() statements should be avoided if there is a good
alternative. Hence this patch. No functionality has been changed.
