[PATCH v3 6/8] qla2xxx: Use scsi_get_sector() instead of scsi_get_lba()

[Bart Van Assche <bvanassche@xxxxxxx>]

Use scsi_get_sector() 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.
