Gleb Smirnoff 65572cade3 unix/dgram: return EAGAIN instead of ENOBUFS when O_NONBLOCK set 
This is behavior what some programs expect and what Linux does.  For
example nginx expects EAGAIN when sending messages to /var/run/log,
which it connects to with O_NONBLOCK.  Particularly with nginx the
problem is magnified by the fact that a ENOBUFS on send(2) is also
logged, so situation creates a log-bomb - a failed log message
triggers another log message.
