scsi: mpt3sas: Get device objects using sas_address & portID

Currently driver retrieves the sas_device/sas_expander objects from
corresponding object's lists using just device's SAS Address.

Make driver retrieve the objects from the corresponding objects list using
device's SAS Address and PhysicalPort (or PortID) number. PhysicalPort
number is the port number of the HBA through which this device is accessed.
