scsi: hisi_sas: Don't fail IT nexus reset for Open Reject timeout

mainline inclusion
from mainline-v5.2-rc1
commit 246ea3c0
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I538BF
CVE: NA

---------------------------------------------------------

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.
