[PATCH] mpt3sas: only one vSES is handy even IOC has multi vSES

Whenever the driver is adding the vSES to virtual-phys list then
the driver is reinitializing this list every time. Hence those
vSES devices which were added earlier to this same list are lost.
So, Even though multiple vSES devices are configured in IOC;
but while scanning the vSES devices driver finds only one vSES device
in the list and hence adds only that device to SML.
So, don't reinitialize this list every time a new vSES device is
added to it.
