The following patch fixes an oops I was seeing on a machine with
misconfigured scsi cables, but could feasibly happen in other paths.
The oops was occurring because scsi_remove_device was getting
called for a device before scsi_add_device had fully completed.
This resulted in sysfs_remove_link being called with a NULL dentry.
