Revert "scsi: fix soft lockup in scsi_remove_target() on module removal"
commit 305c2e71b3d733ec065cb716c76af7d554bd5571 upstream.
Now that we've done a more comprehensive fix with the intermediate
target state we can remove the previous hack introduced with commit
90a88d6ef88e ("scsi: fix soft lockup in scsi_remove_target() on module
removal").
