fat: Opencode sync_page_range_nolock()
fat_cont_expand() is the only user of sync_page_range_nolock(). It's also the
only user of generic_osync_inode() which does not have a file open. So
opencode needed actions for FAT so that we can convert generic_osync_inode() to
a standard syncing path.
Update a comment about generic_osync_inode().
