scsi: target/core: Simplify the code for aborting SCSI commands
Instead of allowing the code that aborts a SCSI command to finish before all iSCSI data frames have been received, make that code wait until all iSCSI data frames have been received. Introduce a new member variable in the target driver template to communicate that information from the iSCSI target driver to the target core. This change allows to leave out the check whether or not it is already safe to send the TASK_ABORTED reply from transport_send_task_abort().
