[PATCH v5 19/23] nilfs2: Convert nilfs_lookup_dirty_node_buffers() to use filemap_get_folios_tag()

["Vishal Moola (Oracle)" <vishal.moola@gmail.com>]

Convert function to use folios throughout. This is in preparation for
the removal of find_get_pages_range_tag(). This change removes 1 call to
compound_head().
