scsi: target: Fold core_tmr_handle_tas_abort() into transport_cmd_finish_abort()
For the two calls to transport_cmd_finish_abort() outside core_tmr_handle_tas_abort() it is guaranteed that CMD_T_TAS is not set. Use this property to fold core_tmr_handle_tas_abort() into transport_cmd_finish_abort(). This patch does not change any functionality.
