Subject: [PATCH v3]kernel.h Move preprocessor #warning about using kernel headers in userpsace to types.h

Move the preprocessor #warning message:
warning: #warning Attempt to use kernel headers from user space, 
see http://kernelnewbies.org/KernelHeaders
from kernel.h to types.h.
And also fixe the #warning message due to the preprocessor not being
able to read the web address due to it thinking it was the start of a comment.
also remove the extra #ifndef _KERNEL_ since it's already there.
