Allocate 96 bytes for SCSI sense data reply
The SCSI layer uses SCSI_SENSE_BUFFERSIZE (96) for the sense buffer size, even though some other code uses "sizeof(struct request_sense)" (which is 64 bytes). Allocate the buffer using the bigger of the two for safety. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
