fs/buffer: add folio_set_bh helper
Patch series "convert create_page_buffers to folio_create_buffers".
One of the first kernel panic we hit when we try to increase the block
size > 4k is inside create_page_buffers()[1]. Even though buffer.c
function do not support large folios (folios > PAGE_SIZE) at the moment,
these changes are required when we want to remove that constraint.
This patch (of 4):
The folio version of set_bh_page(). This is required to convert
create_page_buffers() to folio_create_buffers() later in the series.
