Max Kellermann c460ef6e05 lib/iov_iter: initialize "flags" in new pipe_buffer ...

commit 9d2231c5d74e13b2a0546fee6737ee4446017903 upstream.

The functions copy_page_to_iter_pipe() and push_pipe() can both
allocate a new pipe_buffer, but the "flags" member initializer is
missing.

Fixes: 241699cd72a8 ("new iov_iter flavour: pipe-backed")
