scsi: mpi3mr: Refresh SAS ports during soft reset
Update the host's SAS ports if there is change in port id or phys. If the
port id is changed, then the driver updates it. If some phys are
enabled/disabled during reset, then driver updates them in STL.
Check for the responding expander devices and update the device handle if
it got changed. Register the expander with STL if it got added during reset
and unregister the expander device if it got removed during reset.
[mkp: include fix for zeroday warning]
