huge tmpfs: decide stat.st_blksize by shmem_is_huge()
4.18 commit 89fdcd262fd4 ("mm: shmem: make stat.st_blksize return huge
page size if THP is on") added is_huge_enabled() to decide st_blksize: if
hugeness is to be defined per file, that will need to be replaced by
shmem_is_huge().
This does give a different answer (No) for small files on a
"huge=within_size" mount: but that can be considered a minor bugfix. And
a different answer (No) for default files on a "huge=advise" mount: I'm
reluctant to complicate it, just to reproduce the same debatable answer as
before.
