thp: move shmem_huge_enabled() outside of SYSFS ifdef
The newly introduced shmem_huge_enabled() function has two definitions,
but neither of them is visible if CONFIG_SYSFS is disabled, leading to a
build error:
mm/khugepaged.o: In function `khugepaged':
khugepaged.c:(.text.khugepaged+0x3ca): undefined reference to `shmem_huge_enabled'
This changes the #ifdef guards around the definition to match those that
are used in the header file.
Fixes: e496cf3d7821 ("thp: introduce CONFIG_TRANSPARENT_HUGE_PAGECACHE")
