[dpdk-dev] [PATCH] cmdline: fix warning for unused return value

[Bruce Richardson]

When DPDK is compiled on Ubuntu with extra warnings turned on, there is a
warning about the return value from write() being unchecked. Rather than
having builds disable the warning, which may mask other cases we do care
about, we can add a dummy use of the return value in the code to silence it
in this instance.
