Gleb Smirnoff d2b3a0ed31 sendto: don't clear transient errors for atomic protocols 
The changeset 65572cade3 uncovered the fact that top layer of sendto(2)
would clear a transient error code if some data was copied out of uio.
The clearing of the error makes sense for non-atomic protocols, since
they have sent some data.  The atomic protocols send all or nothing.

The current implementation of unix/dgram uses sosend_generic(), which
would always copyout and only then it may fail to deliver a message.
The sosend_dgram(), currently used by UDP only, also has same behavior.
