vt: don't export vt_kmsg_redirect() to userspace
Fix following warning in linux-next by guarding the function definition
(both the "extern" and the inline) with #ifdef __KERNEL__.
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").
