ata: libata-scsi: add support for the REMOVE ELEMENT AND TRUNCATE command

Browse source

Define the translation for the REMOVE ELEMENT AND TRUNCATE command
(SERVICE ACTION IN command with service action
SAI_REMOVE_ELEMENT_AND_TRUNCATE) into the ATA command
ATA_CMD_REMOVE_ELEMENT_AND_TRUNCATE with the new function
ata_scsi_remove_element_and_truncate_xlat()

The array of supported commands ata_supported_cmds is modified to add a
new entry for this command. ata_scsi_cmd_is_supported() is also modify to
correctly handle this new entry depending on the target device flag
ATA_DFLAG_DEPOP being set.

The ATA command completion is handled using the function
ata_scsi_depop_ua_cap_changed_complete() so that on a successful
completion, a UNIT ATTENTION with the additional sense code set to
CAPACITY DATA HAS CHANGED is raised.
