[SCSI] fix sense buffer length handling problem

Browse source 
The new bio code was incorrectly converted from stack allocated to
kmalloc'd buffer handling.  There are two places where it incorrectly
uses sizeof(*sense) to get the size of the sense buffer.  This
actually produces one, so no sense data was ever getting back, causing
failure in things like disk spin up.
