[DECNET]: fix SIGPIPE
Currently recvmsg generates SIGPIPE whereas sendmsg does not; for the other stacks it seems to be the other way round! It also fixes the bug where reading from a socket whose peer has shutdown returned -EINVAL rather than 0. Signed-off-by: Patrick Caulfield <patrick@tykepenguin.com> Signed-off-by: David S.
