David Howells 2489502fb1 ipv4, ipv6: Use splice_eof() to flush 
[ Upstream commit 1d7e4538a5463faa0b0e26a7a7b6bd68c7dfdd78 ]

Allow splice to undo the effects of MSG_MORE after prematurely ending a
splice/sendfile due to getting an EOF condition (->splice_read() returned
0) after splice had called sendmsg() with MSG_MORE set when the user didn't
set MSG_MORE.

For UDP, a pending packet will not be emitted if the socket is closed
before it is flushed; with this change, it be flushed by ->splice_eof().

For TCP, it's not clear that MSG_MORE is actually effective.
