[PATCH 4/7] iscsi: Use scsi_get_pos() instead of scsi_get_lba()

[Bart Van Assche <bvanassche@acm.org>]

Use scsi_get_pos() instead of scsi_get_lba() since the name of the latter
is confusing. Additionally, use lower_32_bits() instead of open-coding it.
This patch does not change any functionality.
