[PATCH] Don't export vt_kmsg_redirect() to userspace

[Bernhard Walle]

Fix following warning in linux-next by guarding the function definition (both
the "extern" and the inline) with #ifdef __KERNEL__.

------------------------- 8< ----------------------------------------------------
usr/include/linux/vt.h:89: userspace cannot call function or variable defined in
the kernel

Introduced by commit 5ada918b82399eef3afd6a71e3637697d6bd719f ("vt:
introduce and use vt_kmsg_redirect() function").
