[PATCH] libata: fix passthru sense data header
sb[7] should contain the length of whole information sense data descriptor while desc[1] should contain the number of following bytes in the descriptor. ie. 14 for sb[7] but 12 for desc[1]. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
