[PATCH] ARM: thp: fix unterminated ifdef in header file

[Arnd Bergmann]

A recent change accidentally removed one line more than it should
have, causing the build to fail with ARM LPAE:

In file included from /git/arm-soc/arch/arm/include/asm/pgtable.h:31:0,
                 from /git/arm-soc/include/linux/mm.h:55,
                 from /git/arm-soc/arch/arm/kernel/asm-offsets.c:15:
/git/arm-soc/arch/arm/include/asm/pgtable-3level.h:20:0: error: unterminated #ifndef
 #ifndef _ASM_PGTABLE_3LEVEL_H

This puts the line back where it was.

I noticed this on today's linux-next. It's likely that someone else did too
and already submitted a patch, so mine can be ignored. Otherwise please fold
into the original patch.
