net: update consumers of MSG_MORE to recognize MSG_SENDPAGE_NOTLAST
[ Upstream commit d3f7d56a7a4671d395e8af87071068a195257bf6 ] Commit 35f9c09fe (tcp: tcp_sendpages() should call tcp_push() once) added an internal flag MSG_SENDPAGE_NOTLAST, similar to MSG_MORE. algif_hash, algif_skcipher, and udp used MSG_MORE from tcp_sendpages() and need to see the new flag as identical to MSG_MORE. This fixes sendfile() on AF_ALG. v3: also fix udp Reported-and-tested-by: Shawn Landden <shawnlandden@gmail.com> Cc: Tom Herbert <therbert@google.com> Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: David S.
