dpif-netdev: Allow different numbers of rx queues for different ports.
Currently, all of the PMD netdevs can only have the same number of
rx queues, which is specified in other_config:n-dpdk-rxqs.
Fix that by introducing of new option for PMD interfaces: 'n_rxq', which
specifies the maximum number of rx queues to be created for this
interface.
Example:
ovs-vsctl set Interface dpdk0 options:n_rxq=8
Old 'other_config:n-dpdk-rxqs' deleted.
