scsi: hisi_sas: fix SAS_QUEUE_FULL problem while running IO
This patch fix SAS_QUEUE_FULL problem. The test situation is close port while
running IO.
In sas_eh_handle_sas_errors(), SCSI EH will free sas_task of the device if
lldd_I_T_nexus_reset() return TMF_RESP_FUNC_COMPLETE or -ENODEV. But in our
SAS driver, we only free slots of the device when the return value is
TMF_RESP_FUNC_COMPLETE. So if the return value is -ENODEV, the slot resource
will not free any more.
As an solution, we should also free slots of the device in
lldd_I_T_nexus_reset() if the return value is -ENODEV.
