[PATCH] osmo-mgw[master]: network: remove unused return code

[Harald Welte]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/4710

to look at the new patch set (#2).

network: remove unused return code

The function that forwards the tapped (voice ebug) traffic returns
its status (sendto) to the caller. However, none of the callers
seem need this info.

Remove the return code and print an error message on failure

Fixes: Coverity CID#178666
