fs/buffer: add folio_create_empty_buffers helper

Folio version of create_empty_buffers().  This is required to convert
create_page_buffers() to folio_create_buffers() later in the series.

It removes several calls to compound_head() as it works directly on folio
compared to create_empty_buffers().  Hence, create_empty_buffers() has
been modified to call folio_create_empty_buffers().
