If an NCQ error occurs when the IPTT is valid and slot->abort flag is set
in completion path, sas_task_abort() will be called to abort only one NCQ
command now, and the host would be set to SHOST_RECOVERY state. But this
may not kick-off EH Immediately until other outstanding QCs timeouts. As a
result, the host may remain in the SHOST_RECOVERY state for up to 30
seconds, such as follows:

[7972317.645234] hisi_sas_v3_hw 0000:74:04.0: erroneous completion iptt=3264 task=00000000466116b8 dev id=2 sas_addr=0x5000000000000502 CQ hdr: 0x1883 0x20cc0 0x40000 0x20420000 Error info: 0x0 0x0 0x200000 0x0
[7972341.508264] sas: Enter sas_scsi_recover_host busy: 32 failed: 32
[7972341.984731] sas: --- Exit sas_scsi_recover_host: busy: 0 failed: 32 tries: 1

So all NCQ commands that are in the queue should be aborted when an NCQ
error occurs in this scenario.

Fixes: 05d91b557af9 ("scsi: hisi_sas: Directly trigger SCSI error handling for completion errors")
