[PATCH] Protect include/linux/console_struct.h against multiple inclusion.

["Robert P. J. Day" <rpjday@mindspring.com>]

Protect the header file include/linux/console_struct.h against
multiple inclusion, since not doing this causes one of the example
module programs in the Linux Kernel Module Programming Guide to fail
to build due to a bogus "redeclaration" of some structures.
