[PATCH -stable] fix USB_STORAGE_CYPRESS_ATACB

[matthieu castet <castet.matthieu@xxxxxxx>]

Hi,

64a87b244b9297667ca80264aab849a36f494884 broke USB_STORAGE_CYPRESS_ATACB 
translation.

Could it be applied to kernel-stable ?

64a87b244b9297667ca80264aab849a36f494884 commit change the scsi_eh_prep_cmnd logic by making it clear the ->cmnd buffer.

But the sat to cypress atacb translation supposed the ->cmnd buffer wasn't modified.

This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call.
