CVE-2024-57943

In the Linux kernel, the following vulnerability has been resolved: 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().
