scsi: clear unit attention only for REPORT LUNS commands

scsi: clear unit attention only for REPORT LUNS commands

scsi_clear_unit_attention() now only handles REPORTED LUNS DATA HAS
CHANGED.

This only happens when we handle REPORT LUNS commands, so let's rename
the function in scsi_clear_reported_luns_changed() and call it only in
scsi_target_emulate_report_luns().
