Subject: [PATCH] ipc: fix send error handling
According to manpage, ENOBUFS error indicates that either the
input or the output queue is full. This should be considered
an error, but it is treated as an "ignore" condition. Fix the
code to report an error instead.
Fixes: bacaa2754017 ("eal: add channel for multi-process communication")
