scsi: stex: Properly zero out the passthrough command structure
commit 6022f210461fef67e6e676fd8544ca02d1bcfa7a upstream.
The passthrough structure is declared off of the stack, so it needs to be
set to zero before copied back to userspace to prevent any unintentional
data leakage. Switch things to be statically allocated which will fill the
unused fields with 0 automatically.
