  fs/ntfs3: Fix some memory leaks in an error handling path of 'log_replay()'

The ntfs3 filesystem lacks the 'invalidate_folio' method and it causes
memory leak. If you write to the filesystem and then unmount it, the
cached written data are not freed and they are permanently leaked.

log_read_rst() returns ENOMEM error when there is not enough memory.
In this case, if info is returned without initialization,
it attempts to kfree the uninitialized info->r_page pointer. This patch
moves the memset initialization code to before log_read_rst() is called.

When the NTFS BOOT sectors_per_clusters field is > 0x80, it represents a
shift value.  Make sure that the shift value is not too large before using
it (NTFS max cluster size is 2MB).  Return -EVINVAL if it too large.

This prevents negative shift values and shift values that are larger than
the field size.

Prevents this UBSAN error:

 UBSAN: shift-out-of-bounds in ../fs/ntfs3/super.c:673:16
 shift exponent -192 is negative

mpage_readpage still works in terms of pages, and has not been audited
for correctness with large folios, so include an assertion that the
filesystem is not passing it large folios.  Convert all the filesystems
to call mpage_read_folio() instead of mpage_readpage().

After the last patch, Smatch reports:

        fs/ntfs3/file.c:168 ntfs_extend_initialized_size()
        error: uninitialized symbol 'fsdata'.

fsdata is indeed unused.  This is not new, but Smatch couldn't see it
before because calls through pagecache_write_begin()/pagecache_write_end()
could theoretically call any implemention of ->write_begin/write_end,
some of which do use fsdata.  Now that the calls are direct, Smatch can
see they're never used.

Fix this by simply passing NULL.  While ntfs3 does pass this parameter
on to generic functions, those generic functions also never dereference
the fsdata parameter, so it's unnecessary to pass the address of a real
pointer.

There is only one kind of write_begin/write_end aops, so we don't need to
look up which aop it is, just make ntfs_write_begin() and ntfs_write_end()
available to this file and call them directly.
