fs/buffer.c: fold init_buffer() into init_page_buffers()

Since commit e760040 ("fs/buffer.c: remove unnecessary init operation after allocating buffer_head"), there are no callers of init_buffer() outside of init_page_buffers(). So just fold it into init_page_buffers(). Signed-off-by: Eric Biggers <[email protected]> Signed-off-by: Al Viro <[email protected]>
