dpif-netdev: Remove PMD latency on seq_mutex
The PMD thread needs to keep processing RX queues in order
to achieve maximum throughput. It also needs to sweep emc
cache and quiesce which use seq_mutex. That mutex can
eventually block the PMD thread causing latency spikes and
affecting the throughput.
Since there is no requirement for running those tasks at a
specific time, this patch extend seq API to allow tentative
locking instead.
