osmo_io: Make {write,sendto,sendmsg} completion callback optional

There are situations (like multicast datagram transmit) where we don't
really care about the result of a write operation, and hence don't need
a write completion callback.

As the completed message buffer is free'd by core osmo_io, there is no leak
in doing so.
