hfs: Call hfs_write_begin() and generic_write_end() directly
There is only one kind of write_begin/write_end aops, so we don't need to look up which aop it is, just make hfs_write_begin() available to this file and call it directly. Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org> Reviewed-by: Christoph Hellwig <hch@lst.de>
