[SCSI] ibmvscsi: handle re-enable firmware message
New versions of the Power5 firmware can send a "re-enable" message to the virtual scsi adapter. This fix makes us handle the message correctly. Without it, the driver goes catatonic and the system crashes unpleasantly. Signed-off-by: Dave Boutcher <sleddog@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
