target: Add TFO->abort_task for aborted task resources release
Now that TASK_ABORTED status is not generated for all cases by
TMR ABORT_TASK + LUN_RESET, a new TFO->abort_task() caller is
necessary in order to give fabric drivers a chance to unmap
hardware / software resources before the se_cmd descriptor is
released via the normal TFO->release_cmd() codepath.
This patch adds TFO->aborted_task() in core_tmr_abort_task()
in place of the original transport_send_task_abort(), and
also updates all fabric drivers to implement this caller.
The fabric drivers that include changes to perform cleanup
via ->aborted_task() are:
- iscsi-target
- iser-target
- srpt
- tcm_qla2xxx
The fabric drivers that currently set ->aborted_task() to
NOPs are:
- loopback
- tcm_fc
- usb-gadget
- sbp-target
- vhost-scsi
For the latter five, there appears to be no additional cleanup
required before invoking TFO->release_cmd() to release the
se_cmd descriptor.
v2 changes:
- Move ->aborted_task() call into transport_cmd_finish_abort (Alex)
