Subject: Fix a misreporting bug after bioctl -H is used to create a hotspare. 
 This was reported by several people.  What happens is that the firmware
 sometimes misreports what SCSI type a device is.  The driver was only
 allowing a create hotspare function when the type was set to hard disk. 
 Since the firmware will, obviously, not allow the driver to create a hotspare
 on any other type of device the driver doesn't need these smarts and now will
 ignore the type.

Tested by henning todd and Ben Lovett.
