Subject: [PATCH v2] scsi: scsi_transport_sas: add missing newline when printing 'enable' by sysfs

When I cat sysfs file 'enable' below 'sas_phy', it displays as follows.
It's better to add a newline for easy reading.

[root@...alhost ~]# cat /sys/devices/pci0000:00/0000:00:0d.0/0000:0f:00.0/host3/phy-3:2/sas_phy/phy-3:2/enable
1[root@...alhost ~]#
