[PATCH 8/9] scsi: hisi_sas: Don't fail IT nexus reset for Open Reject timeout

[John Garry]

From: Luo Jiaxing <luojiax...@huawei.com>

Currently we call hisi_sas_softreset_ata_disk() in
hisi_sas_I_T_nexus_reset().

If this fails for open reject reason, there is no reason to
fail the IT nexus reset, so only fail for TMF_RESP_FUNC_FAILED.

Some other strings spilled over multiple lines are reunited.
