Yuezhang Mo 98e2fb26d1 exfat: fix the new buffer was not zeroed before writing ...

Before writing, if a buffer_head marked as new, its data must
be zeroed, otherwise uninitialized data in the page cache will
be written.

So this commit uses folio_zero_new_buffers() to zero the new
buffers before ->write_end().

Fixes: 6630ea4910 ("exfat: move extend valid_size into ->page_mkwrite()")
