From: Sreekanth Reddy <sreekanth.reddy@broadcom.com> commit 4c51f956965120b3441cdd39c358b87daba13e19 upstream. Whenever the driver is adding a vSES to virtual-phys list it is reinitializing the list head. Hence those vSES devices which were added previously are lost. Stop reinitializing the list every time a new vSES device is added.
