[PATCH v2] scsi: hisi_sas: display proc_name in sysfs

[Jason Yan]

The 'proc_name' entry in sysfs for hisi_sas is 'null' now becuase it is
not initialized in scsi_host_template. It looks like:

[root@localhost ~]# cat /sys/class/scsi_host/host2/proc_name
(null)

While the other driver's entry looks like:

linux-vnMQMU:~ # cat /sys/class/scsi_host/host0/proc_name
megaraid_sas

 v2: change subject to "display proc_name in sysfs" and add "Acked-by" tag.
