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



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.
