Without a shutdown handler, some cards behave very badly after a kexec.
During probe, pending DMA writes will corrupt kernel memory, for
example.
Using the remove handler guarantees we will use a well tested path.
With this patch I applied, I managed to use kexec multiple times and
probe and SCSI scan worked every time.
