scsi-block: fix direction of BYTCHK test for VERIFY commands
The direction is wrong; scsi_block_is_passthrough returns false for commands that *can* use sglists. Reported-by: Zhang Qian <zhangqian@sangfor.com.cn> Fixes: 8fdc7839e40f43a426bc7e858cf1dbfe315a3804 Cc: qemu-stable@nongnu.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
