As part of clean device removal procedure, user will first
delete the device from Block layer before removing it physically.
When user deletes the device from Block layer then driver set the
corresponding device's starget object as NULL.when user physically
removes the device then driver is not unregistering device with
SCSI Transport Layer (STL) as it unregisters the device only if
the corresponding device's starget is non-NULL and this leads
to unexpected behaviors.

Update the driver to unregister the device with STL even if starget object
is NULL.So that driver can support clean device removal procedure.
