clean up write_begin usage for directories in pagecache
For filesystem that implement directories in pagecache we call block_write_begin with an already allocated page for this code, while the normal regular file write path uses the default block_write_begin behaviour. Get rid of the __foofs_write_begin helper and opencode the normal write_begin call in foofs_write_begin, while adding a new foofs_prepare_chunk helper for the directory code. The added benefit is that foofs_prepare_chunk has a much saner calling convention. Note that the interruptible flag passed into block_write_begin is always ignored if we already pass in a page (see next patch for details), and we never were doing truncations of exessive blocks for this case either so we can switch directly to block_write_begin_newtrunc.
