dpif-netdev: Set PMD load based sleep start/inc to 1 us.
Now that the timer slack for the PMD threads is reduced we can also
reduce the start/increment for PMD load based sleeping to match it.
This will further reduce initial sleep times making it more resilient
to interfaces that might be sensitive to large sleep times.
