commit 6d3a56ed098566bc83d6c2afa74b4199c12ea074 upstream.

While merging mpt3sas & mpt2sas code, we added the is_warpdrive check
condition on the wrong line

---------------------------------------------------------------------------

                        sas_target_priv_data->handle = raid_device->handle;
                        sas_target_priv_data->sas_address = raid_device->wwid;

------------------------------------------------------------------------------

That check should be for the line sas_target_priv_data->raid_device =
raid_device;

Due to above hunk, we are not initializing raid_device's starget for
raid volumes, and so during raid disk deletion driver is not calling
scsi_remove_target() API as driver observes starget field of
raid_device's structure as NULL.
