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
