Hi,

include/scsi/scsi.h defines scsi_to_u32 function like this:

 static inline u32 scsi_to_u32(u8 *ptr)

But the definition of u8 is protected by ifdef __KERNEL__ in asm/types.h hence 
this whole function should be procted as well. This fixes compilation of 
cdrtools with latest kernel-headers GIT tree.
