dpdk: set log write fd to non-blocking
If a PMD writes too many log messages using rte_vlog(), the
pipe for logging can fill and then rte_vlog() will block
on fflush() while it waits for something to read from the other
side of the pipe. That will never happen since the process node
that would read the other side of the pipe runs in the
same thread.
Set the write fd to non-blocking before the call to
rte_openlog_stream(). If the pipe is full, calls to write() or
fflush() will fail but execution will continue.
