scsi: Add scsi_task_process_abort for aborted SCSI tasks.

Browse Source 
Subsequent patches will have to abort SCSI tasks in the iSCSI
layer. But spdk_scsi_task_set_status() API is not public API.

spdk_scsi_task_process_null_lun() is existing public API but
LUN NOT SUPPORTED is not appropriate for those cases.

Hence add an new public API spdk_scsi_task_process_abort().
